In this article, we study the conditions under which having ties that span organizational boundaries (bridging ties) are conducive to the generation of innovations. Whereas previous research has shown that bridging ties have a positive impact on innovative performance, our analysis of 276 R&D scientists and engineers reveals that there are no advantages associated with bridging per se. In contr...

Cohesive subgroups have always represented an important construct for sociologists who study individuals and organizations. In this article, I apply recent advances in the statistical modell ing of social network data to the task of identifying cohesive subgroups from social network data. Further, through simulated data, I describe a process for obtaining the probability that a given sample of ...

In some applications, such as bioinformatics, social network analysis, and computational criminology, it is desirable to find compact clusters formed by a (very) small portion of objects in a large data set. Since such clusters are comprised of a small number of objects, they are extraordinary and anomalous with respect to the entire data set. This specific type of clustering task cannot be sol...

Centrality – Refers to the number of ties one has to others in a network. Those with more ties may have more access to resources contained within the network. Closure – Refers to the interconnections members have with one another, that is, the social ties among the network members that are historical and bridging. Density – Refers to the number and strength of ties among individuals within a so...

Using data from a survey of rural-urban migrants in X City, China, this paper investigates the relationships between migrant-resident ties and migrant integration. Migrant integration is assessed with respect to three dimensions: acculturation, socioeconomic integration, and psychological integration. We divide migrant networks into three categories: kin resident ties, non-kin resident ties, an...

A restriction map of the genomic DNA of Lactobacillus casei phage PL-1 was constructed using the restriction endonucleases BamHI, EcoRI, HindIII, KpnI, NruI and XhoI. The PL-1 genome was 42.2 kb in size and had complementary cohesive ends forming a ring-like monomer. The cohesive ends, analysed with exonuclease III and S1 nuclease, were 3'-terminated single strands protruding from both ends. Th...

Cohesion as an indispensable linguistic feature in discourse analysis and translation has aroused many researchers' interest. To explore the regularity in shifting cohesive devices from English into Chinese our study was designed to analyze the similarities and differences of cohesive devices between English medical texts (EMTs) and their Chinese translation texts (CTTs). A parallel corpus cons...
