It raises what economists call "barriers to entry" to the market for others.
In "Competition Demystified" (Portfolio, $26.95), Mr. Greenwald, with the help of Judd Kahn, has, in essence, examined the five factors that Mr. Porter says make up strategy and has singled out what the authors believe is the most important: a concept that Mr. Greenwald and Mr. Kahn call "barriers to entry".
The training module focuses on improving collaboration and communication between various HCPs, which is practiced by means of a so called barriers and facilitators carousel, in which several small groups of HCPs first discuss the barriers they encounter in collaborating and communicating with each other.
Implementation concepts are designated as including the process of implementation (divided into a series of stages or steps), domains (groups or levels of influences), and three elements: factors (also called barriers and enablers or determinants of practice), strategies (approaches to address the factors and implement the innovation), and evaluations.
Tunneling, also called barrier penetration, in physics, passage of minute particles through seemingly impassable force barriers.
This condition involves the existence of what have come to be called barrier functions.
Electrochemical oxidation of pretreated aluminum foil results in a thin oxide layer called barrier layer alumina (BLA) between the formed PAA and the Al substrate.
The main categories of chemical-and non-chemical flame retardant systems are discussed, so called barrier technologies, their basic mechanisms during fire, and compatibility with natural and polymeric textile materials.
Whereas in basic or neutral electrolytes (ELs) a compact alumina layer is grown, called "barrier" layer, in acidic ELs that can dissolve the oxide a porous alumina layer is grown, on top of a thin (10 100 nm [17]) barrier-type layer.
In this study we investigated the role of PPARα on the expression of genes encoding for transport proteins and phase I/II metabolic enzymes, collectively called barrier proteins, which are responsible for the selective absorption and metabolism of food components.
In large part, this is because of what economists like to call nontariff barriers – but it is exactly such barriers that the agreement under negotiation is supposed to address.
