network theory

A theory, advanced by Niels Jerne and Geoffrey Hoffman, that explains the ability of the immune response to regulate itself. According to the theory, lymphocytes form a network of cells bearing idiotypes, each capable of eliciting anti-idiotype antibodies; each “new” antigen disrupts the balance of an immune network by stimulating an antibody response, which then elicits an anti-idiotype-antibody response, followed by further anti-idiotypes, attenuating and eventually quenching the response to bring the system back into balance. Each antigen receptor or idiotype (of either a T or B cell) is capable of evoking the production of anti-idiotypic cells; these cells, or their products, act to downregulate the production of the original idiotype.

Understanding expressive versus instrumental ties and the different roles within a network is important, but this is just the tip of the iceberg of social network theory. Each situation is different and there is no right or wrong way to solve most problems; understanding the value of networks and the roles people play in those networks allows you to be purposeful about your collaborative efforts, and being intentional can improve collaboration and, therefore, service to patrons in your library.
Further, Table 4 also shows that the ISM literature often utilized several sociological-based theories during this period of time, such as institutional theory and social network theory. This finding contrasts with the state of the literature back in 1990s, which was largely dominated by economic-based theories, such as transaction-cost economics and the RBV (Lu 2003).
We first introduce related concepts on the complex network and the agile supply chain network and then present the evolutionary mechanism of agile supply chain network based on complex network theory and make simulation analysis and then discuss the features of scale-free networks generated with the evolutionary mechanism model.
This weak tie was not strong in terms of social network theory, but it allowed our program to promote our assessment process and findings across three clusters more expeditiously than we would have been able to using only established institutional links.
According to Ator- Network Theory (ANT), human actors are not the only actors that compose the social sphere, since non-human actors are also part of it (Latour, 1994b, 2001, 2005).
Section 2 presents a brief review about modeling of product machining process, complex network theory and its application, and quality monitoring in sensor systems.
The following paragraphs will indicate how the literature on transnational network theory and global administrative law contrast with elements of the positivist view of international law, and how the literature on environmental federalism and non-positivist federalism can be interpreted to contrast with the positivist view.
As tres teorias (Agency Theory, Social Network Theory e Organizational Knowlege Creation) possuem a relacao entre individuos como centralidade.
These settings are interesting for this work, since it purports to use a network theory rarely applied to the theme, and it presents a model that suggests the interface between variables and provides a data collection instrument that allows for the researcher to create inferences and interpretations on a given implementation.
With Policy Networks and Policy Change: Putting Policy Network Theory to the Test, Hugh Compston has attempted to make such a breakthrough.
Prominent examples are the advocacy coalition framework (Sabatier, 1998), social network theory (Freeman, 2006), normalization process theory (May, Mair, Finch, MacFarlane, Dowrick, Treweek et al.
This part of the book is an extremely technical analysis that may be difficult for those who find network theory, hardware, and software discussion intimidating.
