Semiotics, definition

The limitations related to the applicability of Greimas model are twofold. First, as an anal5 tical tool, although Greimas model may appear clear and simple, it may prove to be rather complicated as there are no definitions to identify the actants. The construction of the relationships between the actantial units of the text is always relative, and depends on the researchers definitions. The semiotic analysis requires close assessment and a clear interpretation of the revealed meanings. However, despite the present limitations, the present results support the proposal that Greimas model can be used as a theoretical framework and as practical semiotic tool describing the corporate sustainability . 

Tn the academic literature, the solid-component definition of a co-crystal is frequently accompanied by a reference to a 2005 review paper by Aakeroy and Salmon. This is unfair, since these authors state very clearly in thdr paper that it is not their intention to apply any such definition. Specifically, they write The purpose of this artiele is not to propose new definitions or to weigh in on the current semantic/semiotic debate, but it will be necessary to delineate the scientific realm of this [review] . One criterion applied to limit the realm of the review is that Only co-crystals made from reactants that are solids at ambient eonditions will be included , with an accompanying footnote that states One could also make a ease for including materials such as those prepared through co-condensation (of liquids or gases) at reduced temperatures or elevated pressure . 

We expect that our research results will contribute to strengthen the scientific quality of Semiotic Engineering, by promoting the feedback loop between theory and practice. Additionally, a clearer definition of CEM and SIM can certainly improve the way how they are taught, learned, and professionally practiced, which are more pragmatic contributions of this research.
