On the contrary, say others: in a globalized era, new money defies old concepts of frontiers or nationalities.
The concept of frontier expansion, and the related change of the role of secondary forest in the landscape, typical for colonization areas, does only partly apply to this environment.
Van Gennep (1960) also developed the concept of frontiers associated to margins.
In the context of transboundary issues, this paper introduces a composite water resources allocation approach that integrates both game theory and Pareto frontier concepts over the case of the Euphrates and Tigris Rivers.
Thus, the concept of commodity frontier incorporates two spatial dimensions, a 'space-of-place' and a 'space-of-flows' ([23]: 412).
The concept of resiliency frontier is presented as an upper bound for system resiliency for a given set of possible restoration prioritization strategies.
The multi-attribute frontier concept addresses our lack of knowledge about the relative importance of these multiple drivers of land conversion by objectively combining them into a single-dimensional land clearing pressure metric in a geographical setting.
For O2 reduction, for the oxidation of l-cysteine and of 2-mercaptoethanol when activity (as log k) is compared along the transition series volcano-shaped curves are obtained, which illustrates the concept of 'tuning' frontier orbital energies for maximum reaction rates.
Based on the theoretical finding that the proposed PRP, which is a single-objective optimization problem, can be re-formulated as a dual-objective optimization problem, we develop a solution technique that utilizes the concept of efficient frontier to identify and search the most promising area of the solution space.
As we enter the 21st century, the lack of a space propulsion science discipline – involving the development of new emerging physical theories and models – within the bounds of Rocket Science forbids any rapid development of ideas and concepts toward new frontiers in spaceflight and implies a stagnate death in the advancement of Rocket Science as a whole.
