TL;DR: In this article, the authors outline the mechanism by which brokerage provides social capital, and show that between-group brokers are more likely to express ideas, less likely to have ideas dismissed, and more likely have ideas evaluated as valuable.
Abstract: This article outlines the mechanism by which brokerage provides social capital. Opinion and behavior are more homogeneous within than between groups, so people connected across groups are more familiar with alternative ways of thinking and behaving. Brokerage across the structural holes between groups provides a vision of options otherwise unseen, which is the mechanism by which brokerage becomes social capital. I review evidence consistent with the hypothesis, then look at the networks around managers in a large American electronics company. The organization is rife with structural holes, and brokerage has its expected correlates. Compensation, positive performance evaluations, promotions, and good ideas are disproportionately in the hands of people whose networks span structural holes. The between-group brokers are more likely to express ideas, less likely to have ideas dismissed, and more likely to have ideas evaluated as valuable. I close with implications for creativity and structural change.

TL;DR: This article conducted an extensive literature review, employing bibliometric analysis and snowballing techniques to investigate the state of the art in the field and synthesise the similarities, differences and relationships between both terms.

TL;DR: A review of argument and evidence on the connection between social networks and social capital can be found in this paper, where the authors focus on the network mechanisms responsible for social capital effects rather than trying to integrate across metaphors of social capital loosely tied to distant empirical indicators.

TL;DR: The strength of weak ties is that they tend to be long and connect socially distant locations, allowing information to diffuse rapidly as discussed by the authors, which may explain the widely observed tendency for social movements to diffuse spatially.
Abstract: The strength of weak ties is that they tend to be long—they connect socially distant locations, allowing information to diffuse rapidly. The authors test whether this “strength of weak ties” generalizes from simple to complex contagions. Complex contagions require social affirmation from multiple sources. Examples include the spread of high‐risk social movements, avant garde fashions, and unproven technologies. Results show that as adoption thresholds increase, long ties can impede diffusion. Complex contagions depend primarily on the width of the bridges across a network, not just their length. Wide bridges are a characteristic feature of many spatial networks, which may account in part for the widely observed tendency for social movements to diffuse spatially.

TL;DR: The authors discusses North American and European research from the sociology of valuation and evaluation (SVE), a research topic that has attracted considerable attention in recent years, focusing on subprocesses such as categorization and legitimation, conditions that sustain heterarchies and valuation and evaluative practices.
Abstract: This review discusses North American and European research from the sociology of valuation and evaluation (SVE), a research topic that has attracted considerable attention in recent years. The goal is to bring various bodies of work into conversation with one another in order to stimulate more cumulative theory building. This is accomplished by focusing on (a) subprocesses such as categorization and legitimation, (b) the conditions that sustain heterarchies, and (c) valuation and evaluative practices. The article reviews these literatures and provides directions for a future research agenda.
