“…[15][16][17] Social network theory suggests that highly clustered networks are more effective as information conduits because they improve the ability of collaborating physicians to share information and develop innovative protocols for treatment. 18,19 To the extent that clustering promotes these different forms of teamwork, we hypothesized that it may also lead to improved surgical outcomes.…”

Background-Patients undergoing coronary artery bypass grafting (CABG) must often see multiple providers dispersed across many care locations. To test whether teamwork (assessed with the bipartite clustering coefficient) among these physicians is a determinant of surgical outcomes, we examined national Medicare data from patients undergoing CABG. Methods and Results-Among Medicare beneficiaries who underwent CABG between 2008 and 2011, we mapped relationships between all physicians who treated them during their surgical episodes, including both surgeons and nonsurgeons. After aggregating across CABG episodes in a year to construct the physician social networks serving each health system, we then assessed the level of physician teamwork in these networks with the bipartite clustering coefficient. Finally, we fit a series of multivariable regression models to evaluate associations between a health system's teamwork level and its 60-day surgical outcomes. We observed substantial variation in the level of teamwork between health systems performing CABG (SD for the bipartite clustering coefficient was 0.09). Although health systems with high and low teamwork levels treated beneficiaries with comparable comorbidity scores, these health systems differed over several sociocultural and healthcare capacity factors (eg, physician staff size and surgical caseload). After controlling for these differences, health systems with higher teamwork levels had significantly lower 60-day rates of emergency department visit, readmission, and mortality. Conclusions-Health systems with physicians who tend to work together in tightly-knit groups during CABG episodes realize better surgical outcomes. As such, delivery system reforms focused on building teamwork may have positive effects on surgical care. (Circ Cardiovasc Qual Outcomes. 2016;9:641-648.

“…Aldrich [67] suggested that new ventures benefit from their social capital in the demonstration of legitimacy. The early stage cleantech firms were found to rely more on the social capital of their connections, their investors and current strategic partners when signaling new customers or potential strategic partners.…”

Reveal or Conceal? Signaling Strategies for Building Legitimacy in Cleantech Firms

New entrants in technology-intense industries are in a race to build legitimacy in order to compete with established players. Legitimacy has been identified as a driver of venture survival and growth; it helps mitigate third-party uncertainty and so facilitates access to resources, engagement with customers and other stakeholders. Nevertheless, we know little about how legitimacy is built and how new entrants build legitimacy in complex technology-intensive industries. In this research we explore how Norwegian cleantech firms use signaling and strategic actions to build legitimacy. We analyze five cases while investigating their actions in different phases of the venture's evolution. The results suggest that, contrary to signaling theory expectations, young clean-tech firms do not always build legitimacy by conveying information on their strengths. Instead, we observe that they use signaling strategies to address the specific concerns of different stakeholders. This is very much contingent upon the evolutionary stage of the venture and the firm's current weaknesses.

“…The composition of an entrepreneurial team has decisive impact on its relational capital. From one perspective, it seems reasonable to form an entrepreneurial team with the persons we have strong ties with (Aldrich and Kim, 2007). It helps to avoid the risk connected with the involvement of strangers and allows for capitalizing on friendliness inside the team.…”

“…Team cohesion, respect and trust are necessary conditions for knowledge sharing and innovative decisions (Schenkel and Garrison, 2009). From another point of view, searching for networks based on weaker ties and indirect relations provides a chance to recruit the best experts and gain accurate information, knowledge and expertise (Aldrich and Kim, 2007).…”
