Show moreHuman society operates on large-scale cooperation. However, individual differences in cooperativeness and incentives to free ride on others' cooperation make large-scale cooperation fragile and can lead to reduced social welfare. Thus, how individual cooperation spreads through human social networks remains puzzling from ecological, evolutionary, and societal perspectives. Here, we identify oxytocin and costly punishment as biobehavioral mechanisms that facilitate the propagation of cooperation in social networks. In three laboratory experiments (n = 870 human participants: 373 males, 497 females), individuals were embedded in heterogeneous networks and made repeated decisions with feedback in games of trust (n = 342), ultimatum bargaining (n = 324), and prisoner's dilemma with punishment (n = 204). In each heterogeneous network, individuals at central positions (hub nodes) were given intranasal oxytocin (or placebo). Giving oxytocin (vs matching placebo) to central individuals increased their trust and enforcement of cooperation norms. Oxytocin-enhanced norm enforcement, but not elevated trust, explained the spreading of cooperation throughout the social network. Moreover, grounded in evolutionary game theory, we simulated computer agents that interacted in heterogeneous networks with central nodes varying in terms of cooperation and punishment levels. Simulation results confirmed that central cooperators' willingness to punish noncooperation allowed the permeation of the network and enabled the evolution of network cooperation. These results identify an oxytocin-initiated proximate mechanism explaining how individual cooperation facilitates network-wide cooperation in human society and shed light on the widespread phenomenon of heterogeneous composition and enforcement systems at all levels of life.

Show moreThis paper examines mentorship as a mechanism for individuals to acquire and develop creativity. More specifically, we study the effect of mentor creativity on protégé creativity and how this effect is moderated by the mentoring styles of autonomy and exploration. Our empirical analysis focuses on formal PhD supervision and training, drawing on survey and bibliometric data for 143 life-science professors (mentors) and their 685 PhD students (protégés). We find that the effect of mentor creativity on protégé creativity is insignificant during protégés’ PhD studies but becomes significantly positive after protégés hold faculty positions, suggesting that the mentorship effect takes time to manifest but is enduring. Furthermore, the effect of mentor creativity on protégé creativity is significant only when protégés have high levels of autonomy and exploration during PhD studies. This suggests the importance of autonomy and exploration in the effective transfer of creativity from mentors to protégés. Show less

Show moreChapter 3 examines the decisions that inform the BRI’s institution building.It explores the tension between strategic and effficiency-oriented concerns, tracing these tensions across three issue areas: tax, trade, and development finance. The chapter shows that, in dealing with challenges, the Chinese government lacks an integral governance framework that systemically coordinates all relevant institutions. Instead, it takes varied institutional approaches to overseeing BRI projects, ranging from bilateral trade agreements to multilateral fijinancial institutions. This raises the question of what is driving China’s development of agreements and institutions for the BRI. The chapter argues that China’s development of BRI tax initiatives is mostly motivated by efficiency drivers, its trade agreements with key BRI partners by strategic drivers, and its efforts to establish multilateral financial institutions by both drivers.

Show moreThis paper explores the complex relationship between scientific novelty and technological impact. We measure novel science as publications which make new combinations of prior knowledge, as reflected in new combinations of journals in their references, and trace links between science and technology by scientific references in patent applications. We draw on all the Web of Science SCIE journal articles published in 2001 and all the patents in PATSTAT (October 2013 edition). We find that the small proportion of scientific publications which score on novelty, particularly the 1% highly novel scientific publications in their field, are significantly and sizably more likely to have direct technological impact than comparable non-novel publications. In addition to this superior likelihood of direct impact, novel science also has a higher probability for indirect technological impact, being more likely to be cited by other scientific publications which have technological impact. Among the set of scientific publications cited at least once by patents, there are no additional significant differences in the speed or the intensity of the technological impact between novel and non-novel scientific prior art, but the technological impact from novel science is significantly broader and reaching new technology fields previously not impacted by its scientific discipline. Novel science is also more likely to lead to patents which are themselves novel. Show less
