Engaging college science students and changing academic achievement with technology: A quasi-experimental preliminary investigation

quasi-experimental designs

Carle AC, Jaffee D, Miller D.
GSID: YDqaOvmAFYUJ
AC Carle, D Jaffee, D Miller - Computers & Education, 2009 - Elsevier

… In this pilot study, we used a quasi-experimental design to examine whether a technology enhanced research methods classroom led to increased student engagement and academic achievement among college students. Two features generally characterized the technology …

Quench-induced breathing mode of one-dimensional Bose gases.

Physical review letters

Fang B, Carleo G, Johnson A, Bouchoule I.
PMID: 25083651
Phys Rev Lett. 2014 Jul 18;113(3):035301. doi: 10.1103/PhysRevLett.113.035301. Epub 2014 Jul 15.

We measure the position- and momentum-space breathing dynamics of trapped one-dimensional Bose gases at finite temperature. The profile in real space reveals sinusoidal width oscillations whose frequency varies continuously through the quasicondensate to ideal Bose gas crossover. A comparison...

Effects of low and standard intra-abdominal pressure on systemic inflammation and immune response in laparoscopic adrenalectomy: A prospective randomised study.

Journal of minimal access surgery

Schietroma M, Pessia B, Stifini D, Lancione L, Carlei F, Cecilia EM, Amicucci G.
PMID: 27073301
J Minim Access Surg. 2016 Apr-Jun;12(2):109-17. doi: 10.4103/0972-9941.178513.

BACKGROUND: The advantages of laparoscopic adrenalectomy (LA) over open adrenalectomy are undeniable. Nevertheless, carbon dioxide (CO2) pneumoperitoneum may have an unfavourable effect on the local immune response. The aim of this study was to compare changes in the systemic...

Atom resolved evidence for a defective chemisorbed oxygen state at a Mg(0001) surface.

Chemical communications (Cambridge, England)

Carley AF, Davies PR, Jones RV, Harikumar KR, Roberts MW.
PMID: 12357759
Chem Commun (Camb). 2002 Sep 21;(18):2020-1. doi: 10.1039/b205212a.

A chemisorbed oxygen state has been revealed for the first time by scanning tunnelling microscopy to be present at the interface between a (1 x 1)-O structure and overlying magnesium atoms; the step-height at the interface is between 0.14...

Tunable gold catalysts for selective hydrocarbon oxidation under mild conditions.

Nature

Hughes MD, Xu YJ, Jenkins P, McMorn P, Landon P, Enache DI, Carley AF, Attard GA, Hutchings GJ, King F, Stitt EH, Johnston P, Griffin K, Kiely CJ.
PMID: 16237439
Nature. 2005 Oct 20;437(7062):1132-5. doi: 10.1038/nature04190.

Oxidation is an important method for the synthesis of chemical intermediates in the manufacture of high-tonnage commodities, high-value fine chemicals, agrochemicals and pharmaceuticals: but oxidations are often inefficient. The introduction of catalytic systems using oxygen from air is preferred...

Mutations that Affect Agrobacterium vitis-Induced Grape Necrosis also Alter Its Ability to Cause a Hypersensitive Response on Tobacco.

Phytopathology

Herlache TC, Zhang HS, Ried CL, Carle SA, Zheng D, Basaran P, Thaker M, Burr AT, Burr TJ.
PMID: 18944123
Phytopathology. 2001 Oct;91(10):966-72. doi: 10.1094/PHYTO.2001.91.10.966.

ABSTRACT Tn5-induced mutations in Agrobacterium vitis F2/5 resulted in both altered grape necrosis and tobacco leaf panel collapse phenotypes, suggesting that the underlying mechanisms of the reactions are related. The reaction on tobacco resembles the classical hypersensitive response (HR)...

Switching off hydrogen peroxide hydrogenation in the direct synthesis process.

Science (New York, N.Y.)

Edwards JK, Solsona B, N EN, Carley AF, Herzing AA, Kiely CJ, Hutchings GJ.
PMID: 19229032
Science. 2009 Feb 20;323(5917):1037-41. doi: 10.1126/science.1168980.

Hydrogen peroxide (H2O2) is an important disinfectant and bleach and is currently manufactured from an indirect process involving sequential hydrogenation/oxidation of anthaquinones. However, a direct process in which H2 and O2 are reacted would be preferable. Unfortunately, catalysts for...

Direct synthesis of H(2)O(2) from H(2) and O(2) over gold, palladium, and gold-palladium catalysts supported on acid-pretreated TiO(2).

Angewandte Chemie (International ed. in English)

Edwards JK, Ntainjua E, Carley AF, Herzing AA, Kiely CJ, Hutchings GJ.
PMID: 19802864
Angew Chem Int Ed Engl. 2009;48(45):8512-5. doi: 10.1002/anie.200904115.

A low energy pathway to CuCl2 at Cu(110) surfaces.

Physical chemistry chemical physics : PCCP

Carley AF, Davies PR, Harikumar KR, Jones RV.
PMID: 19924324
Phys Chem Chem Phys. 2009 Dec 14;11(46):10899-907. doi: 10.1039/b914970h. Epub 2009 Oct 07.

The reaction of hydrogen chloride gas with partially oxidised Cu(110) surfaces follows a different structural pathway than its reaction with a clean surface. In the latter case a c(2 x 2)Cl structure develops which is compressed in the [110]...

Effects of the nanostructuring of gold films upon their thermal stability.

ACS nano

Bowker M, Carley AF, Davies PR, Morgan DJ, Crouch J, Lalev G, Dimov S, Pham DT.

ACS Nano. 2010 Apr 27;4(4):2228-32. doi: 10.1021/nn901614e.

We report results relating to the thermal stability of nanoparticles and show a remarkable effect of nanostructuring of the metal. Au films are nanostructured by focused ion beam sputtering (FIB) to produce isolated areas of metal, which are imaged...

We report the behavior of Au nanoparticles anchored onto a Si(111) substrate and the evolution of the combined structure with annealing and oxidation. Au nanoparticles, formed by annealing a Au film, appear to "float" upon a growing layer of...
