We model network formation when heterogeneous nodes enter sequentially and form connections through both random meetings and network-based search, but with type-dependent biases. We show that there is “long-run integration,” whereby the composition of types in sufficiently old nodes’ neighborhoods approaches the global type distribution, provided that the network-based search is unbiased. Howev...

OWING to the association between alcohol and chronic pancreatitis in man' there has,been considerable interest in the effect of alcohol upon gastro-entero pancreatic (GEP) hormones. Previous estimations of GEP hormones following oral alcohol ingestion have shown raised serum gastrin concentrations in response to 18 per cent and 15 per cent ethanol in man (Becker, Reeder and Thompson2), and Stra...

Individuals in many social networks imperfectly monitor other individuals’ network relationships. This paper shows that, in a model of a communication network, imperfect monitoring leads to the existence of many ine cient equilibria. Reasonable restrictions on actions or on beliefs about others’ actions can, however, eliminate many of these ine cient equilibria even with imperfect monitoring. S...

The removal of flexible protein regions is generally used to promote crystallization, but advanced strategies to quickly remove multiple flexible regions from proteins or protein complexes are lacking. Here, it is shown how a protein heterodimer with multiple flexibilities, the RNA polymerase I subcomplex A14/A43, could be crystallized with the use of an iterative procedure of predicting flexib...

In this introduction the editors showcase the papers by way of a structured project and seek to clarify the two key concepts cited in the title. We consider the history of the idea that knowledge is an economic factor, and discuss the question of whether regions provide the relevant system of reference for knowledge-based economic development. Current transformations in university-industry-gove...

We develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts. We show that employment is positively correlated across time and agents. Moreover, unemployment exhibits duration dependence: the probability of obtaining a job decreases in the length of time that an agent has been unemployed. Finally, we examine inequality betwe...

The parameters in Monte Carlo (MC) event generators are tuned on experimental measurements by evaluating the goodness of fit between data and MC predictions. relative importance each measurement is adjusted manually an often time-consuming, iterative process to meet different needs. In this work, we introduce several optimization formulations algorithms with new decision criteria for streamlini...
