Aktivity seniorů ve velkých městech: zdraví, prostor a subjektivní kvalita života

Text prezentuje analýzu vybraných aktivit seniorů v prostředí centrálních částí velkých českých měst. Vycházíme z předpokladu, že aktivity jsou faktorem oživujícím fyzické prostředí a spolu s kvalitou fyzického prostředí představují důležitý příspěvek pro kvalitu života seniorů. Tyto souvislosti ilustrujeme na základě výběrového šetření mezi seniory staršími šedesáti let, žijícími ve čtrnácti velkých městech České republiky. Z analýz vyplývá, že senioři jsou skrze aktivity, které s různou frekvencí provozují, aktivními participanty na venkovním prostředí. Intenzita a variabilita jednotlivých typů aktivit vzešlých z faktorové analýzy je však ovlivněna především narůstajícími zdravotními omezeními, která také nejsilněji působí na zmenšování akčního pole seniora. V našem šetření se také potvrzuje vliv fyzického okolí, ovšem v podstatně menší míře než jsme očekávali. Zejména aktivity typu zaměstnání a volnočasové jsou ovlivněny řadou dalších faktorů, které se zdají spíše souviset s životním stylem jedince a potažmo s jeho kulturním a sociálním kapitálem. Diskusi uzavíráme doporučením pro další výzkum aktivit seniorů ve městech jako důležitého příspěvku k urbánním ekonomikám.The article presents an analysis of selected activities engaged in by seniors older adults in the central areas of large Czech townscities. The authors set out from the assumption that activities are a factor that animate the physical environment and, together with its ? the actual quality of that environment of the physical environment, importantly contribute to the quality of life of seniors. The authors illustrate this on the basis of a sample survey conducted among seniors over the age of sixty living in fourteen large towns around the Czech Republic. The analysis shows that through the activities they engage in seniors are active participants in the rural urban environment. However, the intensity and variability of individual types of activities, asas determined by a factor analysis, are mainly influenced by increasing health limitations, which have the biggest impact on reducing the level and scope of the activities older people engage inactivitiesy of seniors. The survey also confirmed that the physical environment influences the activity of seniors as well, but much less so than the authors expected. Participation inEngagement in ?? eEmployment and leisure-time activities in particular are is? influenced by numerous other factors that are related more to the lifestyle of the individual and, by extension, to the individual’s cultural and social capital. The authors close the discussion with recommendations for further research on the activities of older adultsseniors in towns as an important contribution to urban economies

Age and gender difference in ICT literacy and biometrics knowledge

Accelerated digitalization during the COVID-19 pandemic and the transition from mobile phones to smartphones have increased the need for ICT literacy among the general public, including knowledge of the potential risks and their management. Generally, it is assumed that some population groups are more at risk of being left behind. Original empirical data collected in autumn 2020 as part of the PRECOBI project were used to identify the sociodemographic groups at risk of insufficient knowledge of biometrics and ICT safety. The novelty Biometrics Knowledge and ICT Safety Index (BIKIS index) was constructed to identify these and analyzed in the context of the Czech Republic. The OLS regression shows that the combination of higher age and lower education is associated with the highest risk of digital illiteracy, potentially resulting in digital exclusion. Regarding biometrics and ICT safety knowledge, the age of 50 is the cut-off point, with those with elementary and lower secondary education at a disadvantage compared to those with higher levels of education. The results show that in terms of ICT literacy, old age starts considerably earlier than in other societal contexts, which is important to note when designing ICT and biometrics-related risk mitigation strategies. The role of early life educational attainment should be supported to ensure ICT literacy in later life.Accelerated digitalization during the COVID-19 pandemic and the transition from mobile phones to smartphones have increased the need for ICT literacy among the general public, including knowledge of the potential risks and their management.

Architecture of the trypanosome RNA editing accessory complex, MRB1

Trypanosoma brucei undergoes an essential process of mitochondrial uridine insertion and deletion RNA editing catalyzed by a 20S editosome. The multiprotein mitochondrial RNA-binding complex 1 (MRB1) is emerging as an equally essential component of the trypanosome RNA editing machinery, with additional functions in gRNA and mRNA stabilization. The distinct and overlapping protein compositions of reported MRB1 complexes and diverse MRB1 functions suggest that the complex is composed of subcomplexes with RNA-dependent and independent interactions. To determine the architecture of the MRB1 complex, we performed a comprehensive yeast two-hybrid analysis of 31 reported MRB1 proteins. We also used in vivo analyses of tagged MRB1 components to confirm direct and RNA-mediated interactions. Here, we show that MRB1 contains a core complex comprised of six proteins and maintained by numerous direct interactions. The MRB1 core associates with multiple subcomplexes and proteins through RNA-enhanced or RNA-dependent interactions. These findings provide a framework for interpretation of previous functional studies and suggest that MRB1 is a dynamic complex that coordinates various aspects of mitochondrial gene regulation

Subjective perception of time focusing on short-term activities

The diploma thesis investigates the subjective perception of time, especially the exactness of the interval length estimation, subjective passage of time, in relation to the time perspective, the level of difficulty in emotion regulation and age. Furthermore, the thesis investigates differences in retrospective and prospective paradigm in interval length estimate. Research was conducted online, with a total number of 180 respondents. Data collection had occurred during a 4 month period. Main instruments were the Czech versions of the ZTPI - Zimbardo's time perspective inventory and the DERS-SF-CZ - Difficulty in emotion regulation scale; moreover, for the declaration of subjective passage of time was employed a method of verbal estimation. Subjective interval length was registered after finishing rewriting of two short texts. The results have showed statistically significant relationships between subjective passage of time and age; between the level of difficulty in emotion regulation and subjective passage of time. Amongst the persons orientated onto positive and negative past, there was found a significant relationship between the subjective passage of time and the difficulty in emotion regulation. Results have also shown that the interval length is overestimated in both, prospective and..

Research of biology knowledge of pupils finishing the compulsory education (year 9 of basic school and year 5 of eight-year grammer school

ABSTRACT Doubravová L.: Research of the Natural History Knowledge of 9th Grade Elementary School and 4th Grade High School Pupils Diploma Thesis, 2011 This thesis presents the level of natural history latent knowledge of pupils who have completed compulsory education. The creation of a didactic test and giving it to pupils who finish attending the 9th grade of elementary school and 4th grade at high school are parts of this work. The thesis deals with the comparison of these two groups of respondents. Results evaluation is presented in words and also illustrated by tables and graphs.
