Company and perceiver characteristics influencing willingness to invest in female‐versus male‐led start‐up companies in STEM and non‐STEM fields

STEM and women

GSID: d-z9x4ZCUmIJ
AL Macchione, DF Sacco, M Brown… - Journal of Applied …, 2022 - Wiley Online Library

Given disparities in the number and success of female relative to male‐led businesses, the current program of research tested whether gender‐based company cues, employment sector (Science, Technology, Engineering, and Mathematics [STEM] vs. non‐STEM) and CEO gender lead to disparities...

Comparing the Efficacy of Two Affirmation Interventions to Reduce Stereotype Threat Effects on Women's Math Performance

Stem education interventions

GSID: rMptrilfDG8J
A Macchione - 2021 - aquila.usm.edu

Research demonstrates when math-based gender stereotypes are activated (ie, men are better at math than women), women display comparatively poorer math performance than men, a phenomenon referred to as stereotype threat. The current thesis project evaluated two self-affirmation interventions...

Probing the association of frustrated phosphine-borane Lewis pairs in solution by NMR spectroscopy.

Journal of the American Chemical Society

Rocchigiani L, Ciancaleoni G, Zuccaccia C, Macchioni A.
PMID: 24372401
J Am Chem Soc. 2014 Jan 08;136(1):112-5. doi: 10.1021/ja4119169. Epub 2013 Dec 27.

(19)F,(1)H HOESY, diffusion, and temperature-dependent (19)F and (1)H NMR studies allowed us to unequivocally probe the association between the frustrated PR3/B(C6F5)3 (1, R = CMe3; 2, R = 2,4,6-Me3C6H2) Lewis pairs in aromatic solvents. No preferential orientation is favored,...

Astrophysical constraints on Planck scale dissipative phenomena.

Physical review letters

Liberati S, Maccione L.
PMID: 24785026
Phys Rev Lett. 2014 Apr 18;112(15):151301. doi: 10.1103/PhysRevLett.112.151301. Epub 2014 Apr 14.

The emergence of a classical spacetime from any quantum gravity model is still a subtle and only partially understood issue. If indeed spacetime is arising as some sort of large scale condensate of more fundamental objects, then it is...

Morphological Evolution of Noble Metal Nanoparticles in Chloroform: Mechanism of Switching on/off by Protic Species.

RSC advances

Douglas-Gallardo OA, Gomez CG, Macchione MA, Cometto FP, Coronado EA, Macagno VA, Pérez MA.
PMID: 26889378
RSC Adv. 2015;5(122):100488-100497. doi: 10.1039/C5RA17529A.

The morphological stability/morphological reshaping of noble metal nanoparticles are studied experimentally in order to unravel the chemical mechanisms lying beneath. Gold and silver nanoparticles (AuNPs and AgNPs, respectively) formed in chloroformic environment are used, as model synthetic systems, to...

Heterogenized Water Oxidation Catalysts Prepared by Immobilizing Kläui-Type Organometallic Precursors.

Chemistry (Weinheim an der Bergstrasse, Germany)

Pastori G, Wahab K, Bucci A, Bellachioma G, Zuccaccia C, Llorca J, Idriss H, Macchioni A.
PMID: 27246987
Chemistry. 2016 Sep 12;22(38):13459-63. doi: 10.1002/chem.201602008. Epub 2016 Jun 27.

An efficient heterogenized water oxidation catalyst (2_TiO2 ) has been synthesized by immobilizing the Kläui-type organometallic precursor [Cp*Ir{P(O)(OH)2 }3 ]Na (2, Cp*=1,2,3,4,5-pentamethylcyclopentadienyl ligand) onto rutile TiO2 . Iridium is homogeneously distributed at the molecular and atomic/small cluster level in...

Musculoskeletal manifestations in inflammatory bowel disease.

European journal of internal medicine

Salvarani C, Fornaciari G, Beltrami M, Macchioni PL.
PMID: 10967509
Eur J Intern Med. 2000 Aug;11(4):210-214. doi: 10.1016/s0953-6205(00)00093-5.

Musculoskeletal manifestations are the most common extra-intestinal complication of inflammatory bowel disease (IBD). They are part of the clinical spectrum of spondylarthropathies and include different articular manifestations. In addition to axial symptoms, peripheral findings such as seronegative oligoarthritis, dactylitis,...

Determining accurate molecular sizes in solution through NMR diffusion spectroscopy.

Vapor pressure and aqueous solubility are important parameters used to estimate the potential for transport of chemical substances in the atmosphere. For fluorotelomer alcohols (FTOHs), currently under scrutiny by environmental scientists as potential precursors of persistent perfluorocarboxylates (PFCAs), vapor...
