Social connections that span across diverse urban neighborhoods can support prosperity by mobilizing social capital. However, there is limited evidence on the spatial structure of individual capital inside cities. This paper demonstrates measured online spatially more concentrated for residents lower-income than higher-income neighborhoods. We map micro-geography networks in 50 largest metropol...

We propose a novel cohesive subgraph model called ? -strengthened ( ? , ? ) -core (denoted as -core), which is the first to consider both tie strength and vertex engagement on bipartite graphs . An edge strong if contained in at least butterflies 2 × -bicliques). requires each upper or lower level have ties, given To retrieve vertices of optimally, we construct index I store all -cores. Effecti...

1. Short summary of results of the original research (extended summary see below) At this moment (1 September 2001), about two third of the research period are completed. In accordance with the work plan, the focus has been on theoretical model building in the first two years and will shift to empirical testing and publication of research results in the third year. Articles based on the researc...

Given a set of attributed subgraphs known to be from different classes, how can we discover their differences? There are many cases where collections of subgraphs may be contrasted against each other. For example, they may be assigned ground truth labels (spam/not-spam), or it may be desired to directly compare the biological networks of different species or compound networks of different chemi...

During the past three decades, an estimated 200 million rural residents have moved to urban centers in China. They are "sojourners" in the cities and maintain close ties with their home communities, which we term trans-local ties. This paper examines the relationship between migrants' social ties and their mental health, and contrasts the trans-local ties with migrants' ties in the receiving co...

From a social capital perspective, this article investigates how entrepreneurs in new ventures utilize their managerial ties (consisting of ties with other firms and ties with government) to capture opportunity. We also explore the moderating role of organizational learning (via exploratory learning and exploitative learning) in this process. Drawing on a sample of 159 new ventures, we find tha...

Social networks are important for finding jobs, but which ties are most useful? Granovetter (1973) suggested that “weak ties” are more valuable than “strong ties,” since strong ties have redundant information, while weak ties have new information. Using six million Facebook users’ data we find evidence for the opposite. We proxy for job help by identifying people who eventually work with a pre-...

The complete nucleotide sequence (5793 bp) of the cosmid vector pTL5 and the origin of its genetic components has been determined. Cosmid pTL5, a derivative of cosmid vector pHC79, is composed of genetic components from pBR322, bacteriophage lambda and the hybrid lambdoid bacteriophage Charon (Ch) 4A cohesive ends (cos) region. The Ch4A cos region contains genetic components from two bacterioph...
