This article examines the effect of UN actions on the duration of international crises. Four different types of action – assurance, diplomatic engagement, military involvement, and intimidation – and three different outcomes – compromise, victory, and stalemate – are considered. After building on the existing literature to develop expectations of how a third party like the UN shapes crisis trajectories, hypotheses are tested using the International Crisis Behavior (ICB) data and a new events dataset on UN activity. Results from competing-risks models reveal that UN military involvement does well to decrease the risk of one side achieving victory, and diplomatic engagement increases the ability of the belligerents to reach a compromise in the long run. Moreover, diplomatic engagement accompanied by military involvement substantially hastens the pace of stalemate outcomes. Both tactics, however, have some trade-offs. Military involvement can decrease the sense of urgency for compromise; diplomatic engagement can be used for insincere motives and increase the risk of one-sided victory over time. UN actions of assurance and simple intimidation have considerable shortcomings as crisis management vehicles.

Jasmonates (JAs) are essential signalling molecules that co-ordinate the plant response to biotic and abiotic challenges, as well as co-ordinating several developmental processes. Huge progress has been made over the last decade in understanding the components and mechanisms that govern JA perception and signalling. The bioactive form of the hormone, (+)-7-iso-jasmonyl-l-isoleucine (JA-Ile), is perceived by the COI1–JAZ co-receptor complex. JASMONATE ZIM DOMAIN (JAZ) proteins also act as direct repressors of transcriptional activators such as MYC2. In the emerging picture of JA-Ile perception and signalling, COI1 operates as an E3 ubiquitin ligase that upon binding of JA-Ile targets JAZ repressors for degradation by the 26S proteasome, thereby derepressing transcription factors such as MYC2, which in turn activate JA-Ile-dependent transcriptional reprogramming. It is noteworthy that MYCs and different spliced variants of the JAZ proteins are involved in a negative regulatory feedback loop, which suggests a model that rapidly turns the transcriptional JA-Ile responses on and off and thereby avoids a detrimental overactivation of the pathway. This chapter highlights the most recent advances in our understanding of JA-Ile signalling, focusing on the latest repertoire of new targets of JAZ proteins to control different sets of JA-Ile-mediated responses, novel mechanisms of negative regulation of JA-Ile signalling, and hormonal cross-talk at the molecular level that ultimately determines plant adaptability and survival.

In most work contexts, several performance goals coexist, and conflicts between them and trade-offs can occur. Our paper is the first to contrast a dual goal for speed and accuracy with a single goal for speed on the same task. The Sternberg paradigm (Experiment 1, n = 57) and the d2 test (Experiment 2, n = 19) were used as performance tasks. Speed measures and errors revealed in both experiments that dual as well as single goals increase performance by enhancing memory scanning. However, the single speed goal triggered a speed-accuracy trade-off, favoring speed over accuracy, whereas this was not the case with the dual goal. In difficult trials, dual goals slowed down scanning processes again so that errors could be prevented. This new finding is particularly relevant for security domains, where both aspects have to be managed simultaneously.
