Motivated by the need to understand which are the underlying forces that trigger network evolution, we develop a multilevel theoretical and empirically testable model to examine the relationship between changes in the external environment and network change. We refer to network change as the dissolution or replacement of an interorganizational tie, adding also the case of the formation of new ties with new or preexisting partners. Previous research has paid scant attention to the organizational consequences of quantum change enveloping entire industries in favor of an emphasis on continuous change. To highlight radical change we introduce the concept of environmental jolt. The September 11 terrorist attacks provide us with a natural experiment to test our hypotheses on the antecedents and the consequences of network change. Since network change can be explained at multiple levels, we incorporate firm-level variables as moderators. The empirical setting is the global airline industry, which can be regarded as a constantly changing network of alliances. The study reveals that firms react to environmental jolts by forming homophilous ties and transitive triads as opposed to the non jolt periods. Moreover, we find that, all else being equal, firms that adopt a brokerage posture will have positive returns. However, we find that in the face of an environmental jolt brokerage relates negatively to firm performance. Furthermore, we find that the negative relationship between brokerage and performance during an environmental jolt is more significant for larger firms. Our findings suggest that jolts are an important predictor of network change, that they significantly affect operational returns and should be thus incorporated in studies of network dynamics.

This project discusses the relation between memory and graphic novels, mainly focusing on the ongoing narration of the Vietnam War. It adopts a diachronic and philological approach to reconstruct the history of the medium and its entanglement with war, be it as instrument of propaganda or as a memory project. It follows the development of the medium in Hearst and Pulitzer newspapers, analyzing how mass culture helped consolidating a persuasive ‘war mentality’. It reflects on the role that comics played in the creation of the myth of the ‘good war’. It also shows how the ‘god war’ pattern became increasingly contested during the Vietnam War, following the questioning of the traditional “American values” promoted by the counterculture of the time. Finally, it explores how the narration (and memory) of the Vietnam War has changed after September 11, 2001, and it describes the emergence of graphic narratives written by diasporic Vietnamese graphic artists.
