Legislative Quality Assurance Toolbox in the context of the Czech Republic

Legislative Quality Assurance Toolbox in the context of the Czech Republic Michal Riha Abstract The aim of the rigorosum thesis is to describe and evaluate the tools used for the control of legislation quality ("legislative toolbox") at both the parliamentary and pre-parliamentary stage of the legislative process. The main focus is on the situation in the Czech Republic, although the tools used in other jurisdictions are introduced in order to encourage potential discussion regarding an expansion of the Czech legislative toolbox. The toolbox is shown on the background of the principles of proper law making - for example a sceptic lawmaker approach employed with the aim of securing a stable legal environment. This method helps us better understand the potential conflicts between certain legislative principles; one example can be a clash between the legislative needs and the quality control tool when, for example, a required legislative solution might be slowed down by repeated debates within the Legislative Council due to theoretical marginalities. This example indicates a conflict between the principle of sound legislation and the need for reasonable speed of the legislative process. The author also considers the influence of EU law, which is not usually taken into account, despite the European Union law...Nástroje kontroly kvality legislativy v kontextu České republiky Michal Říha Abstrakt Cílem této práce je popis a zhodnocení nástrojů používaných ke kontrole kvality legislativy v parlamentní i předparlamentní fázi legislativního procesu. Hlavním zájmem je situace v Česku, ale práce se věnuje i představení nástrojů požívaných v jiných státech, aby práce mohla podpořit diskuzi o jejich uplatnění i v tuzemsku. Nástroje jsou představovány na pozadí zásad dobré legislativy, např. přístup skeptického zákonodárce uplatňovaný s cílem zajištění stabilního právního prostředí. Tato zvolená metoda slouží k lepšímu uvědomění si konfliktů mezi některými zásadami, což se v praxi projevuje střetem legislativní reality a konkrétního nástroje, např. případy, kdy potřebný legislativní zásah je opožděn opakovaným projednáváním v Legislativní radě z důvodu dílčího teoretického problému, což ukazuje konflikt zásady rozumnosti a rozumné délky projednávání. Práce také neopomíjí vliv práva Evropské unie, který je zpravidla ponecháván stranou, přestože právo Evropské unie významně ovlivňuje tvorbu práva v členských státech, ať už vlastní legislativní tvorbou nebo přímým efektem. Ideově práce vychází z MacCormickovy teorie o sdílených principech mezi členskými státy. Další ideové zdroje jsou práce Helen Xanthaki.

Ethylene-octene-copolymer with embedded carbon and organic conductive nanostructures for thermoelectric applications

Hybrid thermoelectric composites consisting of organic ethylene-octene-copolymer matrices (EOC) and embedded inorganic pristine and functionalized multiwalled carbon nanotubes, carbon nanofibers or organic polyaniline and polypyrrole particles were used to form conductive nanostructures with thermoelectric properties, which at the same time had sufficient strength, elasticity, and stability. Oxygen doping of carbon nanotubes increased the concentration of carboxyl and C-O functional groups on the nanotube surfaces and enhanced the thermoelectric power of the respective composites by up to 150%. A thermocouple assembled from EOC composites generated electric current by heat supplied with a mere short touch of the finger. A practical application of this thermocouple was provided by a self-powered vapor sensor, for operation of which an electric current in the range of microvolts sufficed, and was readily induced by (waste) heat. The heat-induced energy ensured the functioning of this novel sensor device, which converted chemical signals elicited by the presence of heptane vapors to the electrical domain through the resistance changes of the comprising EOC composites. © 2020 by the authors.Operational Program Research and Development for Innovations - European Regional Development Fund (ERDF)European Union (EU); Operational Program Education for Competitiveness - European Social Fund (ESF); National Budget of the Czech Republic [CZ.1.05/2.1.00/03.0111, CZ.1.07/2.3.00/20.0104]; Fund of Institute of Hydrodynamics [AV0Z20600510

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy

In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes. This is largely because the germline is restricted to relatively few cells buried deep within floral tissues, which makes them difficult to study. To overcome this limitation, we have developed a methodology for live imaging of the germ cell lineage within floral organs of Arabidopsis using light sheet fluorescence microscopy. We have established reporter lines, cultivation conditions, and imaging protocols for high-resolution microscopy of developing flowers continuously for up to several days. We used multiview imagining to reconstruct a three-dimensional model of a flower at subcellular resolution. We demonstrate the power of this approach by capturing male and female meiosis, asymmetric pollen division, movement of meiotic chromosomes, and unusual restitution mitosis in tapetum cells. This method will enable new avenues of research into plant sexual reproduction.Web of Science9art. no. e5254

Seasonal habitat use of three predatory fishes in a freshwater ecosystem

To understand the spatiotemporal overlap in the habitat use of sympatric predators, we studied longitudinal activity and reservoir section and depth use of pike (Esox lucius), pikeperch (Sander lucioerca) and catfsh (Silurus glanis) in the Římov Reservoir, using an autonomous telemetry system for 11 months. We found signifcant diferences among these species in studied parameters that varied considerably over tracked period. Pike consistently used the same sections of the reservoir, while pikeperch and catfsh frequently visited a tributary during the warm season (late spring and early autumn), and moved closer to the dam during the cold season (late autumn to early spring). Pike longitudinal activity was highest in the cold season, pikeperch in the warm season, and catfsh activity peaked in both seasons. Overlap in the depth use among species was higher in the warm season, when all species used the upper layer of the water column, and lower in the cold season, when pikeperch and catfsh used deeper areas. These results demonstrated overlay and temporal variation of habitat use among these predators, as well as potential spatiotemporal space for their direct ecological interactions.

A simple fish-based approach to assess the ecological quality of freshwater reservoirs in Central Europe

The assessment of ecological quality in freshwater ecosystems is a key issue in many countries, but conditions for the development of assessment methodologies are often country-specific. This study proposes a simple methodology for the assessment of the ecological potential of reservoirs based on fish communities using a dataset covering major environmental and pressure gradients in reservoirs in the Czech Republic. Fish data obtained by gillnet sampling were correlated with a proxy of eutrophication as a key indicator of anthropogenic pressure for selecting appropriate fish-based indicators, establishing scoring criteria and developing the index of ecological quality. Expert judgement was also used to select potential fish indicators. Nine indicators were selected for the final fish-based index, fulfilling the criteria required by the Water Framework Directive. Two steps were used to validate the fish-based index quantification of its inter annual stability and sensitivity analysis of individual indicators. Finally, the index was compared to a previously developed general index for Central and Western Europe. Our study demonstrates that a combination of expert judgement and strict validation methods can result in an informative assessment of the ecological conditions, which can help identify conservation and restoration priorities. © P.
