PER合著网络中的链接行为
Linking Behavior in the PER Coauthorship Network
摘要：
有相当大的长期利益，了解合作网络的动态，以及这些网络如何形成和发展随着时间的推移。关于社交网络动态的大部分工作都集中在成熟的社区上。研究新兴社交网络的工作很少，因为很难实时的获得数据。在本文中，我们使用来自新兴科学界的30年数据来研究社交网络发展的关键早期阶段。我们发现，当该领域是非常年轻的，岛屿的个人研究人员在相对孤立的劳动，和合作网络是断开的。30年后，我们看到的不再是一群个体，而是一个真正的协作社区，由一个强大的协作网络联系在一起。然而，这种变化并不是逐渐发生的，\textemdash网络仍然是孤立个体的松散组合，直到2000年代中期，当这些较小的部分突然将自己编织成一个整体。在本文的其余部分，我们考虑了三个因素在这些观察到的结构性变化中的作用：增长，社会规范的变化，以及引入特定领域的会议和期刊等机构。我们有该领域最早期的数据，这一时期包括两个不同机构的引入：第一个特定领域的会议和第一个特定领域的期刊。我们还确定了两个相关的行为转变：与第一次会议一致的合作作者的离散增加，以及既定作者之间的转变，从与外界合作，转向相互合作。这些因素的相互作用使我们能够更广泛地了解协作网络的形成。
英文摘要：
There is considerable long-term interest in understanding the dynamics of collaboration networks, and how these networks form and evolve over time. Most of the work done on the dynamics of social networks focuses on well-established communities. Work examining emerging social networks is rarer, simply because data is difficult to obtain in real time. In this paper, we use thirty years of data from an emerging scientific community to look at that crucial early stage in the development of a social network. We show that when the field was very young, islands of individual researchers labored in relative isolation, and the coauthorship network was disconnected. Thirty years later, rather than a cluster of individuals, we find a true collaborative community, bound together by a robust collaboration network. However, this change did not take place gradually\textemdash the network remained a loose assortment of isolated individuals until the mid-2000s, when those smaller parts suddenly knit themselves together into a single whole. In the rest of this paper, we consider the role of three factors in these observed structural changes: growth, changes in social norms, and the introduction of institutions such as field-specific conferences and journals. We have data from the very earliest years of the field, a period which includes the introduction of two different institutions: the first field-specific conference, and the first field-specific journals. We also identify two relevant behavioral shifts: a discrete increase in coauthorship coincident with the first conference, and a shift among established authors away from collaborating with outsiders, towards collaborating with each other. The interaction of these factors gives us insight into the formation of collaboration networks more broadly.
