Engagement Across The Miles: Using Videoconferencing With Small Groups In Synchronous Distance Courses, Amy Piotrowski, Marla K. Robertson

Teacher Education and Leadership Faculty Publications

This article presents suggestions for conducting small-group work in synchronous distance courses taught using Interactive Videoconferencing (IVC) systems. One challenge of teaching over an IVC system is getting students involved in class activities. The authors share how they have used a videoconferencing tool to break up IVC classes into small groups for discussion activities and get peer feedback on written work. These activities engage students in applying what they are learning and in constructing knowledge through discussion with their peers.

End The Bloody Taxation: Seeing Red On The Unconstitutional Tax On Tampons, Victoria Hartman Nov 2017

End The Bloody Taxation: Seeing Red On The Unconstitutional Tax On Tampons, Victoria Hartman

Northwestern University Law Review

Why was there so much activism in the United States, and across the world, to end the tampon tax in 2016? This Note situates the movement to end the tampon tax within a broader history of feminist activism related to tampons and menstruation. It also analyzes the constitutional dimensions of the tax on feminine hygiene products and serves as a litigation guide for plaintiffs claiming that a state, city, or county sales tax on feminine hygiene products violates the Equal Protection Clause. Lastly, this Note demonstrates the hardships women face paying this tax and encourages state legislatures and city councils …

Species-Specific Metabolism Of Naphthalene And Phenanthrene In 3 Species Of Marine Teleosts Exposed To Deepwater Horizon Crude Oil, Erin Pulster, Kevan Main, Dana Wetzel, Steven Murawski

C-IMAGE Publications

The 2 most abundant polycyclic aromatic hydrocarbons (PAHs) measured in Deepwater Horizon crude oil, naphthalene and phenanthrene, and their associated homologs have both been shown to be acutely toxic in fish. Although fish have a relatively high metabolic capacity for PAHs, hydroxylated PAH (OH-PAH) derivatives formed during the initial metabolic response can negatively impact the health of fish. Species-specific metabolism of naphthalene and phenanthrene was evaluated in 3 marine teleosts, red drum (Scianops ocellatus), Florida pompano (Trachinotus carolinus), and southern flounder (Paralichthys lethostigma). Fish were exposed to Deepwater Horizon crude oil by intraperitoneal injections at time 0 and 48 h, …

Enhanced Optical Coupling And Raman Scattering Via Microscopic Interface Engineering, Jonathan V. Thompson, Brett H. Hokr, Wihan Kim, Charles W. Ballmann, Brian E. Applegate, Javier Jo, Alexey Yamilov, Hui Cao, Marlan O. Scully, Vladislav V. Yakovlev

Physics Faculty Research & Creative Works

Spontaneous Raman scattering is an extremely powerful tool for the remote detection and identification of various chemical materials. However, when those materials are contained within strongly scattering or turbid media, as is the case in many biological and security related systems, the sensitivity and range of Raman signal generation and detection is severely limited. Here, we demonstrate that through microscopic engineering of the optical interface, the optical coupling of light into a turbid material can be substantially enhanced. This improved coupling facilitates the enhancement of the Raman scattering signal generated by molecules within the medium. In particular, we detect at …

Woman and Child Health

Low birthweight (LBW) remains a significant public health problem in Pakistan and further understanding of factors associated with LBW is required. We conducted a hospital-based matched case control study to identify risk factors associated with LBW in a rural district of Pakistan. We found that illiteracy (AOR: 2.68; 95% CI: 1.59 - 4.38), nulliparity (AOR: 1.82; 95% CI: 1.26-2.44), having a previous miscarriage/abortion (AOR: 1.22; 95% CI: 1.06-2.35), having < 2 antenatal care (ANC) visits during last pregnancy (AOR: 2.43; 95% CI: 1.34-2.88), seeking ANC in third trimester (AOR: 3.62; 95% CI : 2.14-5.03), non-use of iron folic acid during last pregnancy (AOR: 2.72; 95% CI: 1.75-3.17), having hypertension during last pregnancy (AOR: 1.42; 95% CI: 1.13-2.20), being anemic (AOR: 2.67; 95% CI: 1.65-5.24) and having postpartum weight of

Effects Of Habitat Fragmentation On Genetic Diversity In Cycas Balansae (Cycadaceae), Tam Nguyen Minh, Trang Nguyen T. Phuong, Giang Vu T. Ha, Triest L. Triest Nov 2017

Effects Of Habitat Fragmentation On Genetic Diversity In Cycas Balansae (Cycadaceae), Tam Nguyen Minh, Trang Nguyen T. Phuong, Giang Vu T. Ha, Triest L. Triest

ASEAN Journal on Science and Technology for Development

Habitat fragmentation is a serious threat to species survival. In Vietnam, Cycas balansae has been considered as threatened species because of the reduction and fragmentation of its habitats and over-exploitation. We assessed genetic variability and the pattern of population structure among six populations sampled in four provinces: Hoa Binh, Ha Nam, Ninh Binh and Quang Ninh. Polyacrylamide gel electrophoresis was performed on leaf tissues from 152 individuals representing 6 populations of C. balansae. Six of twelve enzyme systems were used to estimate genetic diversity at population and species levels. Eleven loci were examined. The allozyme data showed high levels of …

Diversity Of Arthropods In Farmed Wetlands In The Gulf Of Mexico Coastal Plain And Effects Of Detrital Subsidies, Nathan Mercer, Michael D. Kaller, Michael J. Stout Nov 2017

Diversity Of Arthropods In Farmed Wetlands In The Gulf Of Mexico Coastal Plain And Effects Of Detrital Subsidies, Nathan Mercer, Michael D. Kaller, Michael J. Stout

Faculty Publications

© 2016 The Author(s). Wetland acreage has declined continentally in the USA. With the loss of natural wetlands, farmed wetlands may be a surrogate for natural wetlands. Seasonally, flooded rice fields are commonly managed wetlands on the Gulf of Mexico Coastal Plain. This study had two objectives: (1) catalog arthropod diversity in rice fields; (2) investigate if detrital subsidies could elicit trophic cascades that reduce nuisance organisms. In 2013 and 2014, experimental rice plots were established, and detritus was applied to half of the plots in each year. Floating pitfall traps, aquatic D-net sweeping, Gee crawfish traps and root/sediment corers …

Cysteines And N-Glycosylation Sites Conserved Among All Alphaherpesviruses Regulate Membrane Fusion In Herpes Simplex Virus 1 Infection, Paul J.F. Rider, Misagh Naderi, Scott Bergeron, Vladimir N. Chouljenko, Michal Brylinski, Konstantin G. Kousoulas Nov 2017

Cysteines And N-Glycosylation Sites Conserved Among All Alphaherpesviruses Regulate Membrane Fusion In Herpes Simplex Virus 1 Infection, Paul J.F. Rider, Misagh Naderi, Scott Bergeron, Vladimir N. Chouljenko, Michal Brylinski, Konstantin G. Kousoulas

Faculty Publications

© 2017 American Society for Microbiology. Neurotropism is a defining characteristic of alphaherpesvirus pathogenicity. Glycoprotein K (gK) is a conserved virion glycoprotein of all alphaherpesviruses that is not found in other herpesvirus subfamilies. The extracellular amino terminus of gK has been shown to be important to the ability of the prototypic alphaherpesvirus herpes simplex virus 1 (HSV-1) to enter neurons via axonal termini. Here, we determined the role of the two conserved N-linked glycosylation (N48 and N58) sites of gK in virus-induced cell fusion and replication. We found that N-linked glycosylation is important to the regulation of HSV-1-induced membrane fusion …

Habitat Association Predicts Genetic Diversity And Population Divergence In Amazonian Birds, Michael G. Harvey, Alexandre Aleixo, Camila C. Ribas, Robb T. Brumfield Nov 2017

Habitat Association Predicts Genetic Diversity And Population Divergence In Amazonian Birds, Michael G. Harvey, Alexandre Aleixo, Camila C. Ribas, Robb T. Brumfield

Faculty Publications

© 2017 by The University of Chicago. The ecological traits of organisms may predict their genetic diversity and population genetic structure and mediate the action of evolutionary processes important for speciation and adaptation. Making these ecological-evolutionary links is difficult because it requires comparable genetic estimates from many species with differing ecologies. In Amazonian birds, habitat association is an important component of ecological diversity. Here, we examine the link between habitat association and genetic parameters using 20 pairs of closely related Amazonian bird species in which one member of the pair occurs primarily in forest edge and floodplains and the other …

Proprioceptive neurons monitor the movements of limbs and joints to transduce the movements into electrical signals. These neurons function similarly in species from arthropods to humans. These neurons can be compromised in disease states and in adverse environmental conditions such as with changes in external and internal pH. We used two model preparations (the crayfish muscle receptor organ and a chordotonal organ in the limb of a crab) to characterize the responses of these proprioceptors to external and internal pH changes as well as raised CO2. The results demonstrate the proprioceptive organs are not highly sensitive to changes …

Physics Faculty Publications and Presentations

Carborane-capped gold nanoparticles (Au/carborane NPs, 2–3 nm) can act as artificial ion transporters across biological membranes. The particles themselves are large hydrophobic anions that have the ability to disperse in aqueous media and to partition over both sides of a phospholipid bilayer membrane. Their presence therefore causes a membrane potential that is determined by the relative concentrations of particles on each side of the membrane according to the Nernst equation. The particles tend to adsorb to both sides of the membrane and can flip across if changes in membrane potential require their repartitioning. Such changes can be made either with …

Technology-Based? Cost Factoring In U.S. Environmental Standards, Jamison E. Colburn Nov 2017

Technology-Based? Cost Factoring In U.S. Environmental Standards, Jamison E. Colburn

Michigan Journal of Environmental & Administrative Law

Environmental controls in the United States are often said to be “technology-based” because the polluter’s duties are determined by the available technology for controlling that pollution rather than by the social costs and benefits of doing so. Indeed, this is much of what distinguishes U.S. environmental law post-1970 from that which preceded it. But technology-based standards have in fact weighed the costs of controlling pollution in unique, often obscure ways, yielding an analysis that defies standardization and basic notions of transparency. Often lumped under an umbrella heading called “feasibility” analysis and justified on the grounds that it avoids many of …

Lamarck Revisited: The Implications Of Epigenetics For Environmental Law, Michael P. Vandenbergh, David J. Vandenbergh, John G. Vandenbergh Nov 2017

Lamarck Revisited: The Implications Of Epigenetics For Environmental Law, Michael P. Vandenbergh, David J. Vandenbergh, John G. Vandenbergh

Michigan Journal of Environmental & Administrative Law

For generations, a bedrock concept of biology was that genetic mutations are necessary to pass traits from one generation to the next, but new developments in genetics are challenging this fundamental assumption. A growing body of scientific evidence demonstrates that chemical alteration of the way a gene functions, whether through exposure to chemicals, foods or even traumatic experiences, may not only affect the exposed individual, but also the individual’s offspring for two generations or more. This interaction between genes and the environment, known as epigenetics, has revolutionized the understanding of how genes are expressed within an individual and how they …

© 2017 2017 International Pediatric Research Foundation, Inc. BackgroundLongitudinal respiratory syncytial virus (RSV) dynamics have not been well studied despite the existence of factors favoring prolonged RSV replication including high mutation rates allowing rapid evolution and potential escape from immune control. We therefore measured viral load in previously RSV-naive infants over prolonged time spans.MethodsDuring 2014-2015, quantitative nasal aspirates were collected from 51 RSV-PCR+ infants. Multiple parallel assessments of viral loads were quantified at each collected time point using a well-validated real-time quantitative reverse transcriptase polymerase chain reaction assay. After observing viral load rebound phenomenon in some infants, the viral dynamics …

Pseudosasa amabilis (McClure) (Poales: Gramineae) is a typical bamboo species naturally distributed in large area of south China and famous for its culm strength. Although bamboos were found to share the same development rule, the detailed internode morphology of bamboo culm was actually not fully expressed. We explored internode morphology of P. amabilis using 11 different physical parameters in different dimensions (1–4). As Taylor's power law (TPL) is generally applicable to describe relationship between mean and variance of population density, here we used TPL to evaluate the differences between internodes, and further, the relationship between dimension and TPL. Results showed …

Arthropod Development’S Response To Temperature: A Review And New Software For Modeling, Mohammad Ali Mirhosseini, Yaghoub Fathipour, Gadi V.P. Reddy Nov 2017

Arthropod Development’S Response To Temperature: A Review And New Software For Modeling, Mohammad Ali Mirhosseini, Yaghoub Fathipour, Gadi V.P. Reddy

Faculty Publications

Among environmental factors, temperature has a direct and crucial influence on the key life processes of survival, development, reproduction, and movement of poikilothermic animals and hence their population dynamics. The lower and upper temperature thresholds and optimal temperature have ramifications for all major life processes, where within a specific range, a temperature change results in a proportional rise or fall of the rate of any given process. There are some basic approaches for modeling development response to temperature in arthropods. The oldest and most widely used model is a simple linear description of arthropod development in relation to temperature.The linear …

Comparison Of Thermal Performance Equations In Describing Temperature-Dependent Developmental Rates Of Insects: (Iii) Phenological Applications, Pei Jian Shi, Mei Ling Fan, Gadi V.P. Reddy Nov 2017

Comparison Of Thermal Performance Equations In Describing Temperature-Dependent Developmental Rates Of Insects: (Iii) Phenological Applications, Pei Jian Shi, Mei Ling Fan, Gadi V.P. Reddy

Faculty Publications

The developmental times of poikilotherms at different stages are significantly affected by temperature. Most mathematical models describing the temperature-dependent developmental rates of poikilotherms are built according to the experimental data at various constant temperatures. However, these models can also be applied to the developmental rates at variable temperatures. It is more meaningful to use models to predict the occurrence times of pest insects that actually represent the completion for a particular developmental stage (e.g., hatching, pupation, eclosion) under a natural thermal environment. For some developmental stages, insects might experience a period of high temperatures. In this case, skewed bell-shaped nonlinear …

Rodents are globally important pre-harvest pests of rice. In Southeast Asia, rodent damage to growing rice crops is commonly concentrated towards the center of rice fields, away from the field edge, resulting in a clear pattern known as the “stadium effect.” To further understand this behavior of rodent pests and to develop recommendations for future research and management, we examined the relation between giving-up densities (GUDs) and damage patterns. In Tanay, Luzon, Philippines, GUD trays containing pieces of coconut in a matrix of sand were placed at 4 different distances from the field edge to quantify the perceived risk of …
