The roles of participants involved in foster care for a temporary period in Prague and the Central Bohemian Region

in English language This thesis focuses on foster care for a transitional period. The aim of the thesis is to describe the role of foster carers for a transitional period, OSPOD workers and foster family guides in period between the process of taking a foster child for a transitional period and re-transferring to a biological family or one of the long-term types of foster care. The thesis describes foster care for a transitional period and individual roles according to available literature, legislation, methodology and interviews with actors themselves. The partial goal is to find out how participants perceive each other, what they expect, what competencies they should have. Another partial aim of this work is methodological recommendation.v českém jazyce Tato diplomová práce se věnuje pěstounské péči na přechodnou dobu. Cílem diplomové práce je popsat role pěstounů na přechodnou dobu, pracovníků OSPOD a průvodců pěstounských rodin v procesu od přebrání dítěte pěstounem na přechodnou dobu po předání dítěte do biologické rodiny či do jedné z dlouhodobých forem náhradní rodinné péče. Práce detailně popisuje pěstounskou péči na přechodnou dobu a jednotlivé role aktérů pěstounské péče na přechodnou dobu v procesu pěstounské péče na přechodnou dobu dle dostupné literatury, legislativy, metodologie a samotných rozhovorů s aktéry. Dílčím cílem je zjistit, jak se jednotlivým účastníkům daří jejich roli naplňovat, jak se jednotliví aktéři vnímají navzájem, co od sebe očekávají a co by jim pomohlo ke zkvalitnění jejich profese.Katedra sociální práceDepartment of Social WorkFaculty of ArtsFilozofická fakult

Impact of microcystin containing diets on physiological performance of Nile tilapia (Oreochromis niloticus) concerning stress and growth

International audienceDiets containing Microcystis with considerable amounts of the cyanotoxin microcystin-LR (MC-LR) were fed to determine their impact on the physiological performance of the omnivorous Nile tilapia (Oreochromis niloticus) with regard to stress and growth performance. Four different diets were prepared based on a commercial diet (control, MC-5% [containing 5% dried Microcystis biomass], MC-20% [containing 20% dried Microcystis biomass], and Arthrospira-20% [containing 20% dried Arthrospira sp. biomass without toxin]) and fed to female Nile tilapia. Blood and tissue samples were taken after 1, 7, and 28 d, and MC-LR was quantified in gills, muscle, and liver by using high-performance liquid chromatography (HPLC). Only in the liver were moderate concentrations of MC-LR detected. The stress hormone cortisol and glucose were analyzed from plasma, suggesting that all modified diets caused only minor to moderate stress, which was confirmed by analyses of hepatic glycogen. In addition, the effects of the different diets on growth performance were investigated by determining gene expression of hypophyseal growth hormone (GH) and hepatic insulin-like growth factor-I (IGF-I). For all diets, quantitative reverse transcription-polymerase chain reaction (RT-qPCR) demonstrated no significant effect on gene expression of the major endocrine hormones of the growth axis, whereas classical growth data, including growth and feed conversion ratio, displayed slight inhibitory effects of all modified diets independent of their MC-LR content. However, no significant change was found in condition or hepatosomatic index among the various diets, so it seems feasible that dried cyanobacterial biomass might be even used as a component in fish diet for Nile tilapia, which requires further research in more detail
