Sandpiles, Spanning Trees, and Plane Duality
(Society for Industrial and Applied Mathematics, 2015-03-10)
Let G be a connected, loopless multigraph. The sandpile group of G is a finite abelian group associated to G whose order is equal to the number of spanning trees in G. Holroyd et al. used a dynamical process on graphs ...
Teaching With Reacting To The Past-Bringing Role-Immersion Play Into The College Classroom
(Society for Historians of the Gilded Age and Progressive Era, 2015-10-02)
Association between alcohol-impaired driving enforcement-related strategies and alcohol-impaired driving
All states in the U.S. prohibit alcohol-impaired driving but active law enforcement is necessary for effectively reducing this behavior. Sobriety checkpoints, saturation patrols, open container laws, and media campaigns ...
Unraveling the Role of Alkyl F on CH-pi Interactions and Uncovering the Tipping Point for Fluorophobicity
(American Chemical Society, 2015-07-08)
Although fluorine often plays an influential role in molecular recognition, little is known about the effect of aliphatic fluorine on the CH-pi interaction in solution. A series of molecular balances were synthesized that ...
Flexible feeding kinematics of a tropical carnivorous anuran tadpole
Leptodactylus labyrinthicus tadpoles are known predators of anuran eggs and hatchlings, but they are also able to filter-feed in the water column and scrape food off of firm substrates. We evaluated and compared these ...
Comparison of photoinduced reorientation of ortho-, meta-, and para-methyl red-doped nematic liquid crystals on rubbed polyimide
(American Physical Society, 2015-08-28)
We compare the photoinduced reorientation of the easy axis on rubbed polyimide surfaces for the nematic E7 doped with three isomers of methyl red; ortho, meta, and para. Using optical techniques, the angle and the pitch ...
Effects of perfectionism and exercise on disordered eating in college students
Purpose This study examined two dimensions of perfectionism (Standards and Discrepancy), two aspects of exercise (cardiovascular and strength), and the interaction of these variables as predictors of disordered eating ...
Study Drugs and Academic Integrity: The Role of Beliefs About an Academic Honor Code in the Prediction of Nonmedical Prescription Drug Use for Academic Enhancement
(Johns Hopkins University Press, 2016-01-01)
The role of beliefs about academic integrity in college students’ decisions to use nonmedical prescription drugs (NMPDs) in academic settings was examined. In Spring 2012 the authors obtained survey data from 645 participants ...
Taking tadpole biology into the 21st century: a consensus paper from the first tadpoles international workshop
(Sociedade Brasileira de Herpetologia, 2015-07-01)
Adoption of SO₂ emission control technologies - An application of survival analysis
Using data on coal-fired electric power plants, this article investigates the contributing factors affecting the investment decisions on flue-gas desulfurization (FGD), a capital-intensive emission control technology. The ...
