An application of Kingdon's multiple streams model to the issue of institutional care units for infants
Adámková, Kateřina ; Dobiášová, Karolína (advisor) ; Angelovská, Olga (referee)
This bachelor thesis deals with the closure of infant care institutions in the Czech Republic. Its aim is to identify and describe the key moments that led to the decision to stop placing children under the age of three into institutional care. Infant care institutions have been a topic of extensive discussion in Czech society and politics for a long time. Despite significant criticism, these institutions survived through three different electoral periods. Eventually, they were successfully abolished through an amendment to the Act on Social and Legal Protection of Children in 2021. The thesis delves into the realm of public policy within the Chamber of Deputies and beyond, using Kingdon's multiple streams theory. The research is conducted qualitatively, as it seeks to uncover the crucial moments of agenda-setting, proposal advocacy, and the political decision-making motivations, through the perspectives of four members of parliament who were involved in the entire process, as well as one representative from a non-governmental organization that significantly influenced the course of events. Additionally, the thesis includes analytical work with transcripts and other publicly available political documents. The thesis addresses the question of the uniqueness of the last attempt, setting it apart from...

An appropriate method for assessing hydrogel pore sizes by cryo-sem
Adámková, Kateřina ; Trudicová, M. ; Hrubanová, Kamila ; Sedláček, P. ; Krzyžánek, Vladislav
The aim of our work was to examine and describe ultrastructure of the agarose hydrogel and any possible structural concentration dependencies, and to assess the distribution and size of pores of agarose hydrogel in dependence on its concentration. Four concentrations were prepared (0.5 %, 1.0 %, 2.0 % and 4.0 % of dry weight content) and cryo-SEM and turbidimetry methods were executed on wet (original) samples in order to image the ultrastructure and measure the pore sizes within. \nReasonable results were obtained for the wet samples as they were closer to their native state they are usually used for applications in. Cryo-SEM and turbidimetry provided comparable results of pore diameters and allowed to compare pore diameters dependant on the concentrations, moreover, it showed more detailed and realistic structure.

Structure investigation of hydrogels using a cryo-SEM

Hydrogels can be characterized as elastic hydrophilic polymer chains connected in network\nwhich are able to swell notably when exposed to aqueous media by absorbing considerable\namounts of water. Besides being a constituent of living organisms, nowadays, there are\nvarious fields hydrated polymers (e.g. polyvinyl alcohol, collagen, and starch) can be utilized\n– in both biological and non-biological form. Classic examples of such applications are\nhuman health and cosmetics (contact lenses, wound healing dressings and artificial\nreplacement tissues – skin, arterial grafts, cornea and spinal disc replacement), pharmacy\n(drug delivery systems), bioengineering, food industry, agriculture etc. Also, hydrogels\ncan reversibly change their shape when being exposed to a temperature change.
