Purpose – This study aimed to achieve two objectives: First, we verified whether person–organization fit indirectly affected job performance through positive and negative job-related affective well-being to explore potential affective mechanisms underlying these relationships. Second, we examined possible variations in these associations among employees in on-site, hybrid and remote work modalities.
Design/methodology/approach – The cross-sectional survey, involving 804 participants across the three work arrangements, utilized moderated mediation analysis to examine the impact of person–organization fit on job performance, with the mediating role of job-related affective well-being and the moderating effects of work modes.
Findings – The results revealed a positive relationship between fit and performance via positive and negative job-related affective well-being, consistent across all work modalities.
Research limitations/implications – The findings implicate the importance of person–organization fit in enhancing well-being and its consequences in performance behavior and goal attainment. The consistency of this relationship across various forms of work, including remote and hybrid arrangements, suggests their similarity.
Originality/value – This paper substantially contributes to the field and literature in several key aspects. First, we suggest and verify an underlying affective mechanism for the PO fit-job performance relationship. Second, we discuss this mechanism in the context of the broaden-and-build theory of positive emotions, providing theoretical insights into the empirical findings. Last, we incorporate three work modalities to create a more complex model and investigate if the post-pandemic changes observed in the work environment differentiate the fit-performance association discovered in prior research.
Cognitive reappraisal refers to changing how one thinks about a situation to alter its emotional impact. It is central to well-being1 and engages prefrontal regulatory circuits2, prompting the assumption that their activity reflects a person’s capacity to regulate emotions3,4,5. Yet evidence for this assumption remains inconclusive and has not been established at scale. Here we analysed 40 task-based functional magnetic resonance imaging (fMRI) datasets in a preregistered consortium with 2,175 participants and show that three widely used indicators of reappraisal capacity—trait questionnaires, task-based affective ratings and amygdala down-regulation—do not converge on a common core. Moreover, none of the three indicators showed the expected association with canonical prefrontal regulatory circuits. Trait questionnaires showed no detectable neural associations across the brain and task-based affective ratings were instead associated with responses in the amygdala and sensorimotor cortices. At the process level, canonical control circuits were engaged during both emotion generation and reappraisal, challenging their presumed specificity for emotion regulation. These findings caution against using activation in putatively regulatory brain regions to infer how well a person regulates emotions, with implications for neural biomarkers, interventions and psychoeducation that link emotion regulation difficulties to specific regional brain deficits.
We introduce Timed Interleaved Interpreted Systems (TIIS), a dense-time agent-based formalism for modelling executions of timed security protocols under an interleaved discrete semantics. In TIIS, at most one global action is executed at a time—co-executed by all agents that share it, while all remaining components stutter—and time elapse is represented separately. Interleaving thus operates across distinct global actions rather than within a single synchronisation, which reflects asynchronous protocol behaviour more directly than joint-step semantics. We define the syntax and semantics of TIIS and focus on reachability-oriented timed security properties arising in protocol-execution models. We then present a translation from networks of timed automata to TIIS in an environment-owned-clocks normal form and prove that the resulting TIIS structure simulates the timed behaviour of the source network under explicit structural assumptions, and that under the same assumptions the translation preserves reachability in both directions. Finally, we propose a bounded model checking encoding for TIIS based on satisfiability modulo theories (SMT) that separates delay steps from discrete action steps, making the interleaving discipline explicit at the formula level; the encoding is sound and complete for each fixed bound. The approach is implemented within the broader BMC4TimeSec toolchain and evaluated on a large common benchmark corpus of multi-session timed protocol instances. The experiments show full agreement of verification outcomes across the aligned Timed Automata (TA), Timed Interpreted Systems (TIS), and TIIS backends. The timed-automata backend remains the strongest runtime baseline; TIIS is slower than TIS in aggregate runtime, but consistently reduces peak memory consumption, which we explain mechanically at the level of the SMT encoding.

Recent studies suggest that women's divergent thinking, an indicator of creative potential, peaks during ovulation, potentially as a signal to attract mates. However, given that arousal is a key factor facilitating creative cognition, this increase may be a by-product of general heightened arousal during ovulation. This hypothesis has not been fully explored, as most research relies on self-reported measures of arousal, which is a significant limitation. Thus, the role of arousal in linking ovulation to divergent thinking remains unclear. To address this question, we conducted an intraindividual study measuring electrodermal activity (EDA) as a physiological indicator of arousal. Women of reproductive age (N = 69) participated in four sessions involving divergent thinking tasks across different phases of their menstrual cycle. Results indicate that electrodermal reactivity mediates the relationship between menstrual cycle phases and the originality of ideas. Additionally, reducing arousal through relaxation during ovulation decreased idea originality. These findings support the hypothesis that increased state-dependent creative potential during ovulation may be a by-product of heightened arousal.
Low adherence remains a persistent challenge in self-guided internet interventions, and universal strategies are needed to address it. In this study, we designed and evaluated a brief self-guided add-on module aimed at strengthening self-efficacy specific to adhering to internet interventions. The module included a testimonial video and two text-based exercises grounded in self-efficacy theory. It targeted self-efficacy specific to integrating and maintaining use of internet interventions. In Phase 1, university students (N = 217) were randomized to the module or a waitlist control. The aim was to test the immediate effect of the module on internet intervention adherence self-efficacy. In Phase 2, final-year medical students and medical interns (N = 214) were randomized to receive either the module before a two-week self-guided intervention (Med-Stress Student) or the intervention alone. The goal was to test the module in a naturalistic setting. In Phase 1, an independent samples t-test did not detect a between-group difference in adherence self-efficacy. In Phase 2, linear mixed effects models indicated that the groups did not differ in adherence self-efficacy immediately after the module or at posttest. Wilcoxon tests detected no between-group differences in actual adherence. Mixed ANOVAs found no group by time interactions for work engagement or job stress. Job stress decreased from baseline to posttest across both groups, but this uncontrolled change cannot be attributed to the intervention. In conclusion, we found no evidence that the brief, one-time pre-intervention module improved adherence to internet interventions. High attrition in Phase 2 limits this conclusion. Future studies should test whether continuous support improves adherence.
