Are U.S. and French Cultural Differences Reflected in Advertising Appeals?

Using 2 of Hofstede\u27s cultural dimensions (power distance and uncertainty avoidance) associated by the research of Albers-Millers and Gelb with some of Pollay\u27s value appeals used in advertising, this study successfully replicated 3 of 8 dependant relationships when analyzing the content of print magazines in U.S. and France. Going beyond the scope of a highly educated audience in which Hofstede\u27s cultural dimensions were developed and retested, we indirectly found that these 2 dimensions of culture are partially salient in non-business, less elitist environments in the form of value appeals such as dear , untamed , magic , and youth reinforcing the idea that cultural differences can sometimes be empirically tested by contrasting these appeals

DFT-based Conformational Analysis of a Phospholipid Molecule (DMPC)

The conformational space of the dimyristoyl phosphatidylcholine (DMPC) molecule has been studied using Density Functional Theory (DFT), augmented with a damped empirical dispersion energy term (DFT-D). Fourteen ground-state isomers have been found with total energies within less than 1 kcal/mol. Despite differences in combinations of their torsion angles, all these conformers share a common geometric profile, which includes a balance of attractive, repulsive and constraint forces between and within specific groups of atoms. The definition of this profile fits with most of the structural characteristics deduced from measured NMR properties of DMPC solutions. The calculated vibrational spectrum of the molecule is in good agreement with experimental data obtained for DMPC bilayers. These results support the idea that DMPC molecules preserve their individual molecular structures in the various assemblies.Comment: 31 pages, 6 Tables, 4 Figure

Enhanced mercury reduction in the South Atlantic Ocean during carbon remineralization

Highlights • Dissolved gaseous mercury can be calculated from modeled dissolved inorganic carbon. • Modeled dissolved gaseous mercury agrees well with worldwide observations. • Dissolved gaseous mercury is related to depth and macronutrients concentrations. Mercury (Hg) in seawater is subject to interconversions via (photo)chemical and (micro)biological processes that determine the extent of dissolved gaseous mercury (DGM) (re)emission and the production of monomethylmercury. We investigated Hg speciation in the South Atlantic Ocean on a GEOTRACES cruise along a 40°S section between December 2011 and January 2012 (354 samples collected at 24 stations from surface to 5250 m maximum depth). Using statistical analysis, concentrations of methylated mercury (MeHg, geometric mean 35.4 fmol L−1) were related to seawater temperature, salinity, and fluorescence. DGM concentrations (geometric mean 0.17 pmol L−1) were related to water column depth, concentrations of macronutrients and dissolved inorganic carbon (DIC). The first-ever observed linear correlation between DGM and DIC obtained from high-resolution data indicates possible DGM production by organic matter remineralization via biological or dark abiotic reactions. DGM concentrations projected from literature DIC data using the newly discovered DGM–DIC relationship agreed with published DGM observations
