A microcosm experiment to evaluate the influence of location and quality of plant residues on residue decomposition and genetic structure of soil mic…
2007
The effects of location (soil surface vs. incorporated in soil) and nature of plant residues on degradation processes and indigenous microbial communities were studied by means of soil microcosms incubation in which the different soil zones influenced by decomposition i.e. residues, soil adjacent to residues (detritusphere) and distant soil unaffected by decomposition (bulk soil) were considered. Plant material decomposition, organic carbon assimilation by the soil microbial biomass and soil inorganic N dynamics were studied with 13 C labelled wheat straw and young rye. The genetic structure of the community in each soil zone were compared between residue locations and type by applying B- a…
Effect of Cd-containing wood ash on the microflora of coniferous forest humus
2000
The use of wood ash in forestry has been questioned because the cadmium (Cd) concentration of ash, which varies between 1 and 20 mg kg(-1) ash, exceeds the level allowed for fertilizers (3 mg kg(-1)) used in agriculture. To investigate the combined and separated effects of Cd and ash on the forest humus microflora, pumice or wood ash, spiked with a water-soluble (CdCl(2)) or -insoluble (CdO) form of Cd at three levels (0, 400 and 1000 mg kg(-1)), were applied at a fertilization level of 5000 kg ha(-1) in a laboratory microcosm study. The trial consisted of 60 microcosms (five replications per treatment), which were incubated in darkness at +20 degrees C and a constant relative air humidity …
Abundance and activity of nitrate reducers in an arable soil are more affected by temporal variation and soil depth than by elevated atmospheric [CO2]
2011
Elevated atmospheric carbon dioxide concentrations ([CO2]) might change the abundance and the function of soil microorganisms in the depth profile of agricultural soils by plant-mediated reactions. The seasonal pattern of abundance and activity of nitrate-reducing bacteria was studied in a Mini-FACE experiment planted with oilseed rape (Brassica napus). Three depths (0–10, 10–20 and 20–30 cm) were sampled. Analyses of the abundances of total (16S rRNA gene) and nitrate-reducing bacteria (narG, napA) revealed strong influences of sampling date and depth, but no [CO2] effects. Abundance and activity of nitrate reducers were higher in the top soil layer and decreased with depth but were not re…
Jaunākā pirmsskolas vecuma bērnu vārdu krājuma bagātināšana didaktiskajās rotaļās
2018
Bakalaura darba tēma – “Jaunākā pirmsskolas vecuma bērnu vārdu krājuma bagātināšana didaktiskajās rotaļās”. Bakalaura darba autore: Indra Tišanova. Izvēlētās tēmas aktualitāte pamatojama ar to, ka didaktiskās rotaļas pirmsskolas vecuma bērniem rada patīkamas izjūtas, veicina sadarbības un citas nepieciešamās prasmes, tādēļ svarīgi izpētīt, kā ar rotaļu palīdzību var bagātināt bērnu vārdu krājumu. Pētījuma mērķis – teorētiski un praktiski izzināt vārdu krājuma bagātināšanas iespējas didaktiskajās rotaļās jaunākā pirmsskolas vecuma bērniem. Pētījums sastāv no divām daļām – teorētiskā un empīriskā pētījuma. Teorētiskajā daļā pētīti un izzināti latviešu un ārvalstu pedagoģijas un psiholoģijas p…

Teachers and inclusion: an empirical survey on specialist training for support teachers
2019
This paper illustrates the results of an empirical-experimental research conducted as part of the Specialization Course for support activities, held at the University of Palermo in the academic year 2016/17. The survey, concerning the effectiveness of training courses for teachers for the development of active learning, involved 450 teachers and had the main objective of investigating whether there was an actual increase in specific professional skills functional to school inclusion among those who attended the course. Despite leading to different kinds of meaningfulness, the pre/post-test data are evidence of a general positive improvement, highlighting how a student-centred approach has a…
Disease dispersion as a spatial interaction: The case of Flavescence Dorée
2020
International audience; Flavescence dorée is a serious and incurable vine disease transmitted by an insect vector. Focusing on its spatial diffusion and on its control with pesticides, this paper investigates the private strategies of wine producers and their socially optimal counterparts. The socially optimal regulation has to address two externalities regarding private treatment decisions: (a) the insufficient consideration of collective benefits from controlling the vector populations; (b) the failure to take into account environmental damage related to pesticide application. The probability of infection is estimated on French data from a spatial econometric specification. Three alternat…
WATER MASSES EXCHANGE THROUGH THE STRAIT OF SICILY DURING THE LAST DEGLACIAL PERIOD AND THE HOLOCENE
2022
The main goal of this thesis is to explore the inter-basin connection between the eastern and the western Mediterranean (E- and W-Med, respectively) during the last deglacial and Holocene periods (last 15 kyr). The thesis is based on the study of a sediment core recovered at the west flank of Sicily channel (W-Sicily), strategically located under the current path of the surface Atlantic waters and directly below the present-day hydrographic boundary layer between the Eastern Mediterranean Sourced Water (EMSW) and the Western Mediterranean Deep Water (WMDW). This key location allow to explore past changes in both surface and deep water exchange between the E and the W-Med. In this thesis, a …
Próba implementacji techniki rysunku na dowolny temat na grunt praktyki pedagogicznej
2022
Rysunek na dowolny temat jest komunikatem symbolicznym i tak powinien być odczytywany. Służy temu analiza oparta na kryteriach oceny, które są płynne i zależne od intencji badacza. Rozumienie rysunku powinno przebiegać podobnie jak przebiega rozumienie wszystkich wytworów kultury duchowej człowieka. Podstawą rozumienia wytworów kultury jest interpretacja, polegająca na odczytywaniu znaczeń symboli obecnych w tradycji (mity, baśnie) i współczesnej kulturze dziecka (bajki, świat wirtualny, media). Jej celem jest poznanie i (z)rozumienie dziecka. W pracy pedagoga interpretacja rysunku dziecka polega na poszukiwaniu jego sensu poprzez odczytywanie znaczeń symboli występujących we wzajemnych pow…
Measuring the Economic, Environmental, and Social Sustainability of Short Food Supply Chains
2019
The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensiv…
