The purpose of this paper is to develop a systematic literature review on the subject of sustainable supply chain network design during 1990-2016, through a review of 261 papers. In this study, qualitative technique for conducting a systematic literature review was used. To systematize and make the literature review more accurate, content analysis method was used that include data collect...
Recent studies of the demand for sports clearly indicate that stars play an important role in promoting fan interest. However, on theoretical grounds it is controversial if a star’s talent superiority and/or a star’s popularity drive match attendance and hence increase gate revenues. Using longitudinal match attendance data of all clubs in the first German soccer league in a 9-year period, the ...
Bearing the versatility of N-heterocyclic carbene (NHC) ligands, here density functional theory (DFT) calculations unravel the capacity of coordination of a deprotonated NHC ligand (pNHC) to generate a doubly C2,N3-bridged dinuclear complex. Here, in particular the discussion is based on the combination of the deprotonated 1-arylimidazol (aryl = mesityl (Mes)) with [M(cod)(μ-Cl)] (M = Ir, Rh) g...
New sterically encumbered N-heterocyclic carbene catalysts were synthesized and used to polymerize rac-lactide to give highly isotactic polylactide or meso-lactide to give heterotactic polylactide.
Axially chiral mono(NHC)-Pd(II) and mono(NHC)-Au(I) complexes with one side shaped 1,1'-biphenyl backbone have been prepared from chiral 6,6'-dimethoxybiphenyl-2,2'-diamine. The complexes were characterized by X-ray crystal structure diffraction. The Pd(II) complex showed good catalytic activities in the Suzuki-Miyaura and Heck-Mizoroki coupling reactions, and the (S)-Au(I) complexes also showe...
technological innovation, because of its curtail role in socio-economic development is one of the important aspects of governmental policies. in this article technological innovation is studied by an institutional approach. public policy by applying this approach could use norms, regulations and other institutional measures to improve innovations and technological policy. more specifically in t...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
The following is a discussion on the different aspects of the term capacity as well as a brief look at the commonly used capacity definitions in industrial and operations engineering in general and in Civil Aviation in particular. We maintain that quality factors (including more specifically here, safety) must be explicitly considered in runway capacity definition, and accordingly, we provide a...
