    Online safety: tool for teaching socio-culturally disadvantaged children

    Get PDF
    Tato diplomová práce se zabývá problematikou bezpečnosti sociálně znevýhodněných dětí na internetu. Výzkumným šetřením potvrzuje hypotézu, že tyto děti nejsou dostatečně vybavené kompetencemi k předcházení možným rizikům a řešení vzniklých problémů vyplývajících zejména z používání sociálních sítí a moderních komunikačních nástrojů v prostředí internetu. Autorka práce si současně vytyčila za cíl přispět ke zvyšování zmíněných kompetencí u dětí navržením metodiky pro jejich vzdělávání s využitím metod zkušenostní pedagogiky a neformálního vzdělávání. Diplomová práce postupně předkládá nejprve teoretická východiska a výsledky výzkumů na téma bezpečnosti dětí na internetu s důrazem na kyberšikanu, kybergrooming, kyberstalking a sexting. Dále se věnuje problematice sociálního znevýhodnění a vyloučení a přístupům jak státního, tak nestátního sektoru ke vzdělávání takto znevýhodněných dětí. Poslední, praktická část práce shrnuje výsledky výzkumu včetně jeho metodologie. Metodika bezpečného chování dětí na internetu se nachází v příloze práce.

    Age Estimation of Dracaena cinnabari Balf. f. on Socotra Island: A Direct Method to Determine Its Lifespan

    Get PDF
    Background: Dracaena cinnabari is a monocot species that does not form annual tree rings; thus, its age can only be estimated. This species is threatened by low natural regeneration, with an evident absence of younger individuals most likely caused by overgrazing; therefore, knowing trees' ages is important for possible conservation strategies; Methods: Data collection was conducted on the Firmihin Plateau on Socotra Island (Yemen) in 2021, and the diameter at breast height (DBH) of 1077 individuals was measured, the same as those established on monitoring plots 10 years before the current measurement. The 10-year radial stem increment and DBH obtained in 2011 served as a basis for the linear model from which the equations for the age calculation were derived. Results and Conclusions: A direct model of age estimation for D. cinnabari was developed. According to the fit model, the age in the first (10.1-15 cm) DBH class was estimated to be 111 years, while that in the last DBH class (90.1-95 cm) was estimated to be 672 years. The results revealed that the previously used indirect methods for D. cinnabari age estimation were accurate.O

    Research highlights: This study is focused on the germination of Dracaena cinnabari seeds in order to discover the possibility of natural and artificial regeneration of this species. Background and Objectives: This study aimed to determine the optimal temperature for D. cinnabari seed germination, e.g., the temperature at which the germination percentage and germination rate (vitality) are the highest. The objectives of this study are to: (1) determine the optimal temperature for the germination of D. cinnabari seeds, (2) compare the suitability of di_erent seed collection methods, and (3) compare the germination parameters of seeds that were collected from di_erent localities. The results of this study will contribute to obtaining the highest number of seedlings from limited seed material for reforestation of the most endangered localities of D. cinnabari species. Materials and methods: Four seed sections were employed. These sections were directly collected from either the fruits of a cut panicle or the ground and were obtained from different localities that differ in altitude. The seeds were tested in a greenhouse while using Petri dishes at three different temperatures-22, 26, and 30 oC-with four replicates of 25 seeds of each section. ANOVA and the t-test were employed for data analysis. Results: The highest germination percentages (GPs) were achieved at 26 oC and 30 oC, which were 84.6% and 82.5%, respectively. The ANOVA and t-test results showed that the germination index (GI) of the species was relatively higher at a temperature of 30 oC relative to that at other temperatures in the study. Although seeds that were collected from the tree achieved a higher GP, the t-test result showed no significant differences in the GI of D. cinnabari seeds that were collected from the ground and from the tree (p > 0.05). Overall, the findings of this study show that temperature has substantial influence on the germination of seeds of D. cinnabari. Therefore, we recommend a temperature of 30 oC to facilitate the germination of D. cinnabari, as it achieved the highest GI at this temperature relative to that at the other temperatures (22 oCC, 26 oC) applied in this study.O

    Bachelor thesis is focused on germinability of Dracaena cinnabari seeds under different temperature conditions, in addition with seeds collected in different ways and from different localities as well. At first, a germination process is described and in addition the factors that have a substantial effect on seed germination and germinability. In another part of the work the methods that are used for germinability testing under laboratory conditions are presented. And in the last part of this section there are summarized current informations about germinability of D. cinnabari seeds and other species of Dracaena genus and related genus Sansevieria. In the practical part, four seed sections were used. These sections were collected either directly from the fruits of a cut panicle or from the ground, and moreover they were from different localities differing in altitude. The sections were named as PL, SB, NN, PE. Seeds were tested in Petri dishes under three different temperatures - 22, 26 and 30 °C, where 4 replicates of 25 seeds of each section were used. The highest germinability was achieved at 26 °C and 30 °C (of 2nd attempt) with germinability 84,6 % and 82,5 % respectively. In addition, a germination energy was calculated for each test. Seeds showed the highest germination energy at 26 °C. The results show a higher germinability of D. cinnabari seeds particularly at higher temperatures. The germinability was evaluated also for individual seed sections and because the sections were collected in different ways and from different localities, the influence of both of these factors was assessed on resulting seed germinability. Finally is concluded that this species probably has a relatively high potential ability of natural regeneration, implying that there is also a potential for regeneration of populations by an artificial way

    Thesis "Citizens' trust in health system CR" discusses the current state of czech health system, how is perceived by the citizens. In this thesis the focus is on the functioning of modern medicine. The theoretical part is devoted to the wider context of the problem of trust in the health care system. This section is trying to describe the changes in society which has been changing relationship of a doctor and patient. Most significant changes that affect this relationship are represented by the development of information society, as well as commercial and system pressure on the doctor. It also highlighted the importance there is the of human rights related to health and patient rights. The empirical part focuses on the research results and their discussion. The research method was applied in the form of qualitative interviews, which were then rewritten and clarified schematically using tables. Research results did not confirm the assumption that citizens lose trust in medicine as a science (lege artis). Problems of the health system respondents associate more with its wrong settings, which can be blamed for the Ministry of Health. Citizens were fairly unsatisfied with the current political situation and this is surely reflected the results of the decreased trust in state institutions

    Project and establishment of forest nursery on Socotra Island - transfer of European forestry know-how

    Diploma thesis is focused on establishment of forest nurseries and seedling production on Socotra Island where a natural regeneration of many endemic species is limited by overgrazing and has been moreover affected by cyclone that hit the island in 2015. Planting stock of Dracaena cinnabari, Boswellia elongata, Boswellia ameero, Boswellia dioscorides, Punica protopunica, Aloe perryi and mangrove Avicennia marina was planned to be propagated in nurseries located in three areas of interest – Firmihin, Homhil and Niyt. Therefore data about the species seed germination or growth rate were gathered and mentioned in the literature section. The species selection was always firstly preceded by dendrological survey of the area. Individual pilot areas were also described together with climatic data and moreover, soil samples were analysed as the substrate for the seedling production comes from local sources. Finally, the projects for forest nurseries establishment were created and according to them were individual nurseries established
