Smolová, Kateřina ; Manková, Denisa (advisor) ; Čípková, Pavla (referee)
Bedtime procrastination is a recently researched phenomenon that in adolescence contributes to poor sleep quality and duration. Sleep procrastination has most often been researched in relation to self-regulation, self-efficacy, and general procrastination. More recently, studies have emerged that focus more on health characteristics in relation to this phenomenon. The aim of the current study was to research the relationship between bedtime procrastination in a Czech adolescent population and sleep quality, sleep duration, chronotype, social jet-lag, gender, and place of residence (city/village). Another aim was to discover the contents and reasons leading individuals to sleep procrastination. The study was conducted using an online questionnaire completed by N = 396 respondents aged 15-18 years. Pearson correlations showed a strong positive relationship (r = .56, p < .001) between sleep procrastination rate and sleep quality, as well as negative relationship with sleep duration (r = -.41, p < .001), strong negative relationship with chronotype (r = -.56, p < .001), and a weak positive relationship with social jet-lag (r = .27, p < .001). Results indicate that the more adolescents procrastinate, the worse sleep quality, shorter sleep duration, higher levels of social jet-lag and evening chronotype,...
Psychological intervention in long-term space missions
Klosová, Matylda ; Bahbouh, Radvan (advisor) ; Čípková, Pavla (referee)
The present bachelor thesis proposes a system of psychological intervention for long-term space missions, based on techniques promoting team performance and coherence. These missions present a number of technological, psychological and psychosocial challenges caused by the prolongation of the time and distance of the flight, during which specific environmental factors are also at work. Intervention methods increase team efficiency and performance, strengthen relationships, and also reduce the likelihood of human error, which is critical to long-term mission success. The theoretical part discusses examples of work in specific environments and possible support mechanisms or facilitating factors. It also opens the topic of the importance of intervention techniques in space environments and the historical context of Czech space research. The research project elaborates on the author's proposal to train crew members in order to increase their autonomy and ability to predict and subsequently resolve possible complications at the level of relationships, bonds and communication. The proposal is set in the upcoming fourth phase of the international SIRIUS 22/23 study and presents possible methods to measure the effectiveness of the intervener's influence, which by their use support psychosocial space research.
