Morningness–Eveningness and Risk Taking

ABSTRACT. Depending on individual differences in biological rhythms and diurnal preferences, people have long been described as either “larks” or “owls.” Larks and owls differ greatly in personality aspects, but from the behavioral perspective it is unclear whether they have significant differences in terms of risky behaviors. Whether morning types or evening types are consistently more risk-taking or risk-averse in different domains remains unknown. This study adopted a general American adult sample to systematically investigate the relationship between chronotype and individuals’ risky behaviors in different domains. By using different methods to measure risky behaviors in different domains, the current research obtained convergent results that morningness was negatively related only to financially risky behaviors for American adults. More specifically, by using the composite scale of morningness and the domain-specific risk attitude scale, Study 1 showed that for American adults, morning types were less likely than evening types to engage in financially risky behaviors (N = 212). In Study 2, after scenario-based methods were used to measure risky behavior, results showed that that participants engaged less in risky behaviors in the domains of gambling and investment (N = 187). A mediator test showed that the negative relationship between morningness and financially risky behaviors was partly mediated by individuals’ self-control ability (self-control scale, Study 1).     

Emergent social identity and observing social support predict social support provided by survivors in a disaster: Solidarity in the 2010 Chile earthquake

Survivors of disasters commonly provide each other with social support, but the social‐psychological processes behind such solidarity behaviours have not been fully explicated. We describe a survey of 1240 adults affected by the 2010 Chile earthquake to examine the importance of two factors: observing others providing social support and social identification with other survivors. As expected, emotional social support was associated with social identification, which in turn was predicted by disaster exposure through common fate. Observing others' supportive behaviour predicted both providing emotional social support and providing coordinated instrumental social support. Expected support was a key mediator of these relationships and also predicted collective efficacy. There was also an interaction: social identification moderated the relationship between observing and providing social support. These findings serve to develop the social identity account of mass emergency behaviour and add value to disaster research by showing the relevance of concepts from collective action.     

Objecting (to) Infrastructure: Ecopolitics at the Ukrainian Ends of the Danube

Abstract

In southern Ukraine, two hydraulic infrastructures continue to exist despite environmentalist campaigns that have exposed them as fragile, broken, or unprofitable. The Danube–Dnister Irrigation Project, a Soviet mega-project that diverted water from the Danube and turned the Sasyk estuary into a reservoir, receives state funding despite a 1994 ban on its use for irrigation. The Bystre Shipping Canal, built in 2004 despite domestic and international opposition, is losing money but continues to operate. These cases exemplify the material politics of infrastructuring in which infrastructure is understood as an antagonistic process of assembling networks of humans and nonhumans rather than a fixed facility. This approach helps explain how the confluence of unruly coastal matters and the politics of expertise have facilitated the re-embedding of these shipping and irrigation infrastructures’ in bureaucratic networks. These cases show that obduracy and fragility, as well as visibility and invisibility—conditions that figure prominently in infrastructure studies—should be considered in terms of oscillation rather than as ontologically distinct or static conditions. This analysis highlights the limits of the modernist search for scientific certainty in resolving environmental conflicts in Ukraine, and some possibilities to experiment politically with new decision-making procedures. This account can thus point beyond reform impulses that re-enact modernist narratives of progress within a strict nature-society divide.
