Fairness and Opportunity in Stem Contexts: Gender, Stereotypes, and Moral Judgments

STEM and diversify

Hoffman AJ, Mulvey KL.
GSID: s7DYTEsS9fsJ
KL Mulvey, AJ Hoffman, L McGuire - Handbook of Moral …, 2006 - taylorfrancis.com

This chapter reviews the literature on fairness, inclusion, and equity in science, technology, engineering, and math (STEM) contexts, with particular attention to gender. Globally, girls and women have been and continue to be underrepresented in STEM fields. In this...

The Development of Gender Stereotypes about Academic Aptitude among European French and North African French Boys

STEM and boys

Hoffman AJ, Kurtz-Costes B.
GSID: HY3E39Q11AYJ
AJ Hoffman, B Kurtz-Costes, F Dumas… - European Journal of …, 2021 - Taylor & Francis

In most Western countries, girls outperform boys in academic engagement, scholastic achievement, and school completion. In the current study, researchers assessed the developmental trajectories of European French and North African French boys'(N= 549; M age= 11.9 years) perceptions of...

Photonic materials, structures and devices for Reststrahlen optics.

Optics express

Feng K, Streyer W, Zhong Y, Hoffman AJ, Wasserman D.
PMID: 26698791
Opt Express. 2015 Nov 30;23(24):A1418-33. doi: 10.1364/OE.23.0A1418.

We present a review of existing and potential next-generation far-infrared (20-60 μm) optical materials and devices. The far-infrared is currently one of the few remaining frontiers on the optical spectrum, a space underdeveloped and lacking in many of the...

Ferromagnetic Coupling in "Double-Bridged" Dihydrogenpyrophosphate Complexes of Cobalt(II) and Nickel(II).

Inorganic chemistry

Greenfield TJ, Hoffman AE, Marino N, Goos AG, Lloret F, Julve M, Doyle RP.
PMID: 26103521
Inorg Chem. 2015 Jul 06;54(13):6537-46. doi: 10.1021/acs.inorgchem.5b00866. Epub 2015 Jun 23.

Three isostructural compounds of the formula {[M(bipy)(H2O)(H2P2O7)]2·2H2O} [bipy = 2,2'-bipyridine; M = Ni (1), Co (2), Mn (3)] have been isolated from aqueous solutions containing the corresponding metal(II) chloride hydrate with a bipy and sodium pyrophosphate solution in a...

Monitoring Charge Separation Processes in Quasi-One-Dimensional Organic Crystalline Structures.

Nano letters

Popescu A, Younts RA, Hoffman B, McAfee T, Dougherty DB, Ade HW, Gundogdu K, Bondarev IV.
PMID: 28873308
Nano Lett. 2017 Oct 11;17(10):6056-6061. doi: 10.1021/acs.nanolett.7b02471. Epub 2017 Sep 11.

We perform the transient absorption spectroscopy experiments to investigate the dynamics of the low-energy collective electron-hole excitations in α-copper phthalocyanine thin films. The results are interpreted in terms of the third-order nonlinear polarization response function. It is found that,...

Investigation of the Unusual Electronic Structure of Pyrococcus furiosus 4Fe Ferredoxin by EPR Spectroscopy of Protein Reduced at Ambient and Cryogenic Temperatures.

Inorganic chemistry

Telser J, Davydov R, Kim CH, Adams MW, Hoffman BM.
PMID: 11671103
Inorg Chem. 1999 Jul 26;38(15):3550-3553. doi: 10.1021/ic990209h.

The hyperthermophilic archaeon Pyrococcus furiosus contains a novel ferredoxin (Pf-Fd) in which, in the native 4Fe form, three of the Fe ions are coordinated to the protein by cysteinyl thiolato ligands, but the fourth Fe is coordinated by an...

Super-Charged Porphyrazines: Synthesis and Physical Properties of Octacationic Tetraazaporphyrins.

Inorganic chemistry

Anderson ME, Barrett AG, Hoffman BM.
PMID: 11671325
Inorg Chem. 1999 Dec 27;38(26):6143-6151. doi: 10.1021/ic990410s.

We report the synthesis of octacationic macrocycles based on the porphyrazine (tetraazaporphyrin) core. The first stage is the synthesis of Mg(II) 2,3,7,8,12,13,17,18-octakis(4-pyridyl)porphyrazine, [Mgpz(pyr)(8)], and the parent [H(2)pz(pyr)(8)]. Both compounds are freely soluble in aqueous acid due to protonation of...
