The paper deals with scientific approaches to the definition of state agrarian policy and concretization in law. Through sphere, law-making decisions are analyzed, thus expanding clarifying subject legislative regulation using mechanism concretization. author believes that legal provisions is necessary because, once implemented, it ensures quality efficiency system. A formal legal, systemic met...

The basic reproduction number R0 is, by definition, the expected life time number of offspring of a newborn individual. An operationalization entails a specification of what events are considered as "reproduction" and what events are considered as "transitions from one individual-state to another". Thus, an element of choice can creep into the concretization of the definition. The aim of this n...

ion and concretization could also be performed with respect to other parameters, not only spatial location. For example the mechanisms for saccade target position (LIP, FEF, superior SC) are separated from mechanisms that are responsible for saccade execution timing (basal ganglia). One could say that the spatial representation of a saccade target is abstracted from its timing, and vice versa. ...

Many models in economics are very unrealistic. At the same time, economists put a lot of effort in making their models more realistic. I argue that in many cases, including the Modigliani-Miller irrelevance theorem investigated in this paper, the purpose of this process of concretization is explanatory. When evaluated in combination with their assumptions, a highly unrealistic model may well be...

Semantics Similar to concrete semantics:  A complete lattice (L#, ≤) as the domain for abstract elements  A monotone function F# corresponding to the concrete function F  Then the abstract semantics is the least fixed point of F#, lfp F# If F# “correctly approximates” F, then lfp F# “correctly approximates” lfp F.

Let S be a topological semihypergroup. As it is known for hypergroups, the lack of an algebraic structure on a semihypergroup pause a serious challenge in extending results from semigroups. We use the notion of concretization or pseudomultiplication, to prove some results on weak convergence of the sequence of averages of convolution powers of probability measures on topological semihypergroups...
