The application of the service loose coupling and the service abstraction principles helps in attaining design-time autonomy as their application results in services whose contracts are shielded from their logic and implementation and hence, the services could be redesigned without affecting their service consumers.

He helped pioneer the sociological new institutionalism, stressing the role of loose coupling in organizational behavior and the conditions under which the diffusion of practices takes place ( e . g . " Organizational Environments ", with W . Richard Scott, Sage 1983 ).

Loose coupling in Weick's sense is a term intended to capture the necessary degree of flex between an organization's internal abstraction of reality, its theory of the world, on the one hand, and the concrete material actuality within which it finally acts, on the other.

Loose coupling is necessary to enable the train to bend around curves and is an aid in starting heavy trains, since the application of the locomotive power to the train operates on each car in the train successively, and the power is thus utilized to start only one car at a time.

This loose coupling between producers and consumers enhances modularity compared to explicit signaling between threads . " Composable Memory Transactions " took this a step farther with its "'retry "'command ( discussed above ), which can, at any time, abort the transaction and wait until " some value " previously read by the transaction is modified before retrying.

While the Django philosophy implies loose coupling, the template filters and tags assume one engine implementation, and both the auth and admin bundled applications require the use of the internal ORM . None of these filters or bundled apps are mandatory to run a Django project, but reusable apps tend to depend on them, encouraging developers to keep using the official stack in order to benefit fully from the apps ecosystem.

The same ALU that is used to execute arithmetic and logic instructions is also used to calculate effective addresses . ( There is a separate adder for adding a shifted segment register to the offset address, but the offset EA itself is always calculated entirely in the main ALU . ) Furthermore, the loose coupling of the EU and BIU ( bus unit ) inserts communication overhead between the units, and the four clock period bus transfer cycle is not particularly streamlined . ( Contrast the two clock period bus cycle of the 6502 CPU and the 80286's three clock period bus cycle with pipelining down to two cycles for most transfers . ) Most 8088 instructions that can operate on either registers or memory, including common ALU and data-movement operations, are at least four times slower for memory operands than for only register operands.
