The impact of chronotype on mental health and subjective well-being: the mediating role of emotion regulation strategies
(Taylor & Francis, 2025-09-22) Gorgol-Waleriańczyk, Joanna
Multiple studies have shown that individuals with an evening chronotype tend to report greater mental health problems, such as higher levels of depression and reduced well-being, compared to those with a morning chronotype. The adverse outcomes associated with eveningness appear to be linked to a combination of biological, social, and psychological factors. In the present study, we investigated the relationship between chronotype and two emotion regulation strategies: cognitive reappraisal and expressive suppression. Furthermore, we explored whether these strategies mediate the association between chronotype and indicators of mental health and well-being. Participants completed the Composite Scale of Morningness (CSM), and based on the established chronotype cut-off criteria, 76 individuals were classified as morning types and 81 as evening types. The total sample consisted of 157 participants (107 women, 50 men; aged 19-42 years, M ± SD: 25.12 ± 4.53 years). All participants completed questionnaires assessing emotion regulation strategies, depressive symptoms, life satisfaction, and positive and negative affect. Evening types scored lower in cognitive reappraisal and well-being, and higher in expressive suppression and depressive symptoms. Controlling for age and gender, we found significant mediation effects, showing that the relationship between chronotype and depressive symptoms and between chronotype and subjective well-being might stem from lower cognitive reappraisal and higher expressive suppression among evening types. These findings suggest that adaptive emotion regulation strategies can positively impact well-being and reduce depressive symptoms, especially among evening types. These findings highlight the importance of targeted interventions to improve emotion regulation strategies in this population.

How do national governments shape and control cities’ international cooperation? Metagovernance analysis of city diplomacy
(Sage, 2026-01-29) Gawłowski, Robert; Szpak, Agnieszka; Modrzyńska, Joanna; Modrzyński, Paweł; Dahl, Michał
Cities play an increasingly important role in international relations and are indispensable in solving global challenges. In this context, the authors have been wondering to what extent they can interact autonomously on the international stage, and what tools do national governments use to shape and control their actions? This paper uses the meta-governance approach to examine intergovernmental relations in the context of cities’ international relations. The authors reveal that states mostly rely on a full range of hands-off tools rather than hands-on ones. Attempts to hierarchically regulate cities’ international relations are limited and depend on the country’s context. Furthermore, the authors reveal that informational tools play a dominant role in intergovernmental relations and are rarely the result of strategic policy structuring by the state government. These findings have important implications for future efforts to address the multi-level governance approach in the context of cities’ international cooperation.
Horror VR as a tool supporting the emotional training of students of the uniformed services. Results of a research experiment
(Springer Nature, 2025) Majewska, Kamila
One of the most popular video game genres that have been attracting the attention of players for years is horror games. Their unique character is that they evoke a range of strong emotions. From a VR perspective, the above game genre gains a new, and more immersive dimension and, as a result, enables particularly intense experiences. The presented research was a pedagogical experiment and was conducted in 2024. The results covered a group of 140 players – students of the uniformed services. The selection for the research was intentional. The study used a quantitative-and-qualitative method. The collected data showed that VR horror games evoke statistically significantly higher levels of emotions such as fear, disgust, vigilance, ecstasy, and admiration, compared with PC horror games. According to the respondents, this tool supports learning how to manage stress, panic, and negative emotions, while offering an interesting and credible form of presentation.
Consequently, it may be applied in emotional training. Compared with traditional training methods, VR horror provides a more immersive, emotionally intense experience, suggesting potential added value in this respect. Statistical calculations were performed using the Student’s T test and the Mann Whitney U test. During the analyses, the mean, mode, as well as the minimum, and maximum values were also determined. This study is not without limitations. It includes a relatively small and homogeneous sample limited to Polish students of the uniformed services. These constraints should be taken into account when interpreting the findings.
Development of a chromatographic method for the analysis of risdiplam in serum extracts
(Taylor and Francis, 2026-01) Balińska, Natalia; Lemska, Anna; Mazurkiewicz-Bełdzińska, Maria; Studzińska, Sylwia
Background: Risdiplam has been used to treat spinal muscular atrophy for three years. There are limited number (4) of papers devoted to its analytics. Until now, risdiplam and its metabolites have only been analyzed using a C18 column, while the sample preparation method involved only protein precipitation.
Research design and methods: Risdiplam was analysed using reversed-phase UHPLC. The experiment was designed to compare the retention of risdiplam on five columns using various mobile phases. The protein precipitation was used as the sample preparation method.
Results: Risdiplam shows greater retention on phenyl columns, where π-π interactions take part in retention. The increasing of mobile phase pH caused increased risdiplam retention, while salt concentration had no significant effect. An octadecyl column with pentafluorophenyl groups was selected with a mobile phase containing 10 mM ammonium formate (pH 4) and acetonitrile. The method was characterized by good linearity, precision, repeatability, and short analysis time. It was applied to risdiplam analysis in serum samples after protein precipitation with different solvents. Finally, proteins were effectively precipitated using 10% TFA solution, providing 90% recovery.
Conclusions: The developed procedure of extraction and determination of risdiplam is simple, fast, accurate, and reliable. It may find application for routine monitoring of risdiplam or for quality control.
