Visual abilities and misconceptions about plate tectonics

discipline specific instruction (e.g., engineering curriculum, social science teachers, geology pedagogy)

Sibley DF.
GSID: oA9cAjZRs_oJ
DF Sibley - Journal of Geoscience Education, 2005 - Taylor & Francis

Diagrams, drawings, and pictures are prototypical representations of concepts. Students' drawings of their concepts of convergent plate boundaries provided an efficient means of …

SK Riffell, DH Sibley - Journal of College Science Teaching, 2003 - search.proquest.com

To improve large lecture courses, we designed a hybrid instructional format that couples online homework with in-class, active learning exercises. We assessed student perceptions …

Nonequilibrium molecular dynamics simulations of nanoconfined fluids at solid-liquid interfaces.

The Journal of chemical physics

Morciano M, Fasano M, Nold A, Braga C, Yatsyshin P, Sibley DN, Goddard BD, Chiavazzo E, Asinari P, Kalliadasis S.
PMID: 28668055
J Chem Phys. 2017 Jun 28;146(24):244507. doi: 10.1063/1.4986904.

We investigate the hydrodynamic properties of a Lennard-Jones fluid confined to a nanochannel using molecular dynamics simulations. For channels of different widths and hydrophilic-hydrophobic surface wetting properties, profiles of the fluid density, stress, and viscosity across the channel are...

Quantitative assessment of placental morphology may identify specific causes of stillbirth.

BMC clinical pathology

Ptacek I, Smith A, Garrod A, Bullough S, Bradley N, Batra G, Sibley CP, Jones RL, Brownbill P, Heazell AE.
PMID: 26865834
BMC Clin Pathol. 2016 Feb 09;16:1. doi: 10.1186/s12907-016-0023-y. eCollection 2016.

BACKGROUND: Stillbirth is frequently the result of pathological processes involving the placenta. Understanding the significance of specific lesions is hindered by qualitative subjective evaluation. We hypothesised that quantitative assessment of placental morphology would identify alterations between different causes of...

Impact of dialect use on a basic component of learning to read.

Frontiers in psychology

Brown MC, Sibley DE, Washington JA, Rogers TT, Edwards JR, MacDonald MC, Seidenberg MS.
PMID: 25852581
Front Psychol. 2015 Mar 24;6:196. doi: 10.3389/fpsyg.2015.00196. eCollection 2015.

Can some black-white differences in reading achievement be traced to differences in language background? Many African American children speak a dialect that differs from the mainstream dialect emphasized in school. We examined how use of alternative dialects affects decoding,...

New Fe(III)-mediated radical cascade reactions of cyclopropyl silyl ethers.

Organic letters

Booker-Milburn KI, Jones JL, Sibley GE, Cox R, Meadows J.
PMID: 12659585
Org Lett. 2003 Apr 03;5(7):1107-9. doi: 10.1021/ol0341703.

[reaction: see text] Fe(III)-mediated ring opening of cyclopropyl ethers bearing a phenyl-substituted butenyl side chain leads to the generation of beta-keto radicals that undergo 5-exo cyclization followed by a novel cascade sequence resulting in the formation of tricyclic ethers.

High-triplet-energy dendrons: enhancing the luminescence of deep blue phosphorescent iridium(III) complexes.

Journal of the American Chemical Society

Lo SC, Harding RE, Shipley CP, Stevenson SG, Burn PL, Samuel ID.
PMID: 19919142
J Am Chem Soc. 2009 Nov 25;131(46):16681-8. doi: 10.1021/ja903157e.

Solution-processable blue phosphorescent emitters with high luminescence efficiency are highly desirable for large-area displays and lighting applications. This report shows that when a fac-tris[1-methyl-5-(4-fluorophenyl)-3-n-propyl-1H-[1,2,4]triazolyl]iridium(III) complex core is encapsulated by rigid high-triplet-energy dendrons, both the physical and photophysical properties can...

Plants, endosymbionts and parasites: Abscisic acid and calcium signaling.

Communicative & integrative biology

Nagamune K, Xiong L, Chini E, Sibley LD.
PMID: 19513200
Commun Integr Biol. 2008;1(1):62-5. doi: 10.4161/cib.1.1.6106.

It was recently discovered that the protozoan parasite, Toxoplasma gondii produces and uses the plant hormone, abscisic acid (ABA), for communication. Following intracellular replication, ABA production influences the timing of parasite egress from the host cell. This density-dependent signal...

On the moving contact line singularity: asymptotics of a diffuse-interface model.

The European physical journal. E, Soft matter

Sibley DN, Nold A, Savva N, Kalliadasis S.
PMID: 23515762
Eur Phys J E Soft Matter. 2013 Mar;36(3):26. doi: 10.1140/epje/i2013-13026-y. Epub 2013 Mar 22.

The behaviour of a solid-liquid-gas system near the three-phase contact line is considered using a diffuse-interface model with no-slip at the solid and where the fluid phase is specified by a continuous density field. Relaxation of the classical approach...

Monitoring antimalarial drug resistance: Applying lessons learned from the past in a fast-moving present.

International journal for parasitology. Drugs and drug resistance

Sibley CH, Price RN.
PMID: 24533274
Int J Parasitol Drugs Drug Resist. 2012 Apr 20;2:126-33. doi: 10.1016/j.ijpddr.2012.03.004. eCollection 2012 Dec.

The need for robust surveillance of antimalarial drugs is more urgent than it has ever been. In the western region of Cambodia, artemisinin resistance has emerged in Plasmodium falciparum and threatens to undermine the efficacy of highly effective artemisinin...

Terrorist attacks escalate in frequency and fatalities preceding highly lethal attacks.

PloS one

Martens A, Sainudiin R, Sibley CG, Schimel J, Webber D.
PMID: 24755753
PLoS One. 2014 Apr 22;9(4):e93732. doi: 10.1371/journal.pone.0093732. eCollection 2014.

Highly lethal terrorist attacks, which we define as those killing 21 or more people, account for 50% of the total number of people killed in all terrorist attacks combined, yet comprise only 3.5% of terrorist attacks. Given the disproportionate...
