On analyse dans cet article les caracte ristiques du leadership efficace en Iran, puis on envisage les liens possibles entre ce profil de leadership et les dimensions culturelles du pays. A partir des donne es fournies par 300 managers provenant de plus de 60 organisations relevant de trois secteurs industriels, on commence par utiliser les dimensions du projet GLOBE pour e valuer la culture iranienne dont les scores sont compare s aÁ ceux d'autres pays. S'appuyant aÁ la fois sur l'emic et l'etic du leadership, les auteurs de veloppent sept dimensions du leadership: encourageant, dictatorial, visionnaire, familial, modeste, loyal et re ceptif. Ils soutiennent que certaines de ces dimensions traduisent les aspects universels (ou etic) du leadership (e ncourageant, dictatorial), alors que d'autres proceÁ dent de l'emic, c'est-aÁ -dire de la spe cificite culturelle du leadership (modeste, familial, loyal). Les re sultats sont discute s en terme de positionnement de la culture iranienne entre des entrelacements fondamentaux et des traditions culturelles complexes. On aborde enfin la question des retombe es sur les recherches aÁ venir.
In this research, silica nano-particles are deposited over the borosilicate glass and silicon wafer substrates by indigenously developed Aerosol impact deposition assembly using SiH4, oxygen, and helium as precursors. The coating process involves deionization of gases leading towards nucleation sites for silica in the presence of plasma, while tuning the pressure difference between reaction and deposition chamber controls the coating thickness, porosity, and refractive index. The deposited coating layer on the substrate enhanced the transmittance to 99.6% at 600 nm wavelength. The induced porous nature and the graded index of the coated layer as observed from the AFM and SEM resulted in superhydrophilic behavior with a water contact angle of near to 0°. The super-hydrophilicity of the coating contains self-cleaning properties, suggesting an improvement of the performance of solar PV modules as well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
