Język(i) w przestrzeni publicznej w świetle teorii socjologicznej i badań empirycznych. Casus młodzieży Śląska Opolskiego
2020
opennessThe article is devoted to the social dimension of linguistic phenomena occurring in Opole region. The Signum specificum of this region consists of: the dialect as a criterion for delimiting the Silesian group and the German language with the related issue of bilingualism. The aim of the article is to present the scope of research conducted by sociologists from Opole on the subject of the diverse linguistic phenomena occurring in the region. The article GWI2DZstates the theoretical and methodological assumptions of the new project of sociological research on bilingualism and multilingualism in the region, and presents the results of a pilot study conducted in 2019 among high school s…
Evaluating the impact of public subsidies on a firm's performance : a two-stage quasi-experimental approach
2009
In this paper we evaluate the effectiveness of regional R&D public programs in Catalonia (Spain) with a two-stage procedure. Firstly, we compare the performance of publicly subsidised companies (treated) with that of similar, but unsubsidised companies (non-treated). We use the Propensity Score Matching (PSM) methodology to construct a control group which, with regard to its observable characteristics, is as similar as possible to the treated group, and that allows us to identify firms which maintain the same propensity to receive public subsidies. Secondly, and once a valid comparison group has been established, we compare the respective performance of each firm using regression techniques…
One-pot synthesis of fluorinated 2-amino-pyrimidine-N-oxides. Competing pathways in the four-atom side-chain rearrangements of 1,2,4-oxadiazoles
2006
Abstract Trifluoromethylated 2-amino-pyrimidine N-oxides have been synthesized by reaction of the 3-amino-5-methyl-1,2,4-oxadiazole with trifluoromethyl-β-diketones in the presence of perchloric acid, followed by hydrolysis. In this ring-to-ring transformation an initial formation of (unisolated) 1,2,4-oxadiazole-pyrimidinium salts, and subsequent ring-opening at the oxadiazole moiety occurs. Isolation of 2-(hydroxyamino)-pyrimidine from the reaction mixture evidenced the presence of a competing pathway where the N(4) nitrogen of the oxadiazole is involved in the formation of a regioisomeric pyrimidinium salt. The effect of the trifluoromethyl group on the product distribution is discussed.…
Attēla fona nošķiršanas paņēmieni objektu izcelšanai
2016
Objektu atpazīšana un analīze ir fundamentāla problēma attēlu apstrādē. Attēlā esošo objektu analīze ir ikdienišķa procedūra mūsdienu attēlu analīzē un apstrādē. Objektu izcelšanas risinājumi ir svarīgi tālākā objektu analīzē un apstrādē, piemēram cilvēku, mašīnu un citu svarīgu objektu, kas satur informāciju izcelšanai attēlā. Bakalaura darbā „Attēla fona nošķiršanas paņēmieni objektu izcelšanai” tiek apskatīti esošie fona nošķiršanas paņēmieni. Šie paņēmieni tiek aprakstīti teorētiski un arī pārbaudīti praktiski uz dažādiem ieejas datiem. Tiek veikta šo metožu salīdzināšana pēc noteiktiem kritērijiem.
Search strategies in innovation networks: The case of the Hungarian food industry
2020
In the food sector, open innovation has become of particular interest. This paper considers open innovation search strategies in the food and beverages industry and examines the probability of using different innovation sources with respect to the type of innovation. Although the information search for new ideas, tools and solutions in the innovation process regarding the scope and depth is well explored and interpreted in the literature, the probability of using the different sources with respect to type of innovation is rarely investigated. To answer these questions, first a probit, then OLS regression model is adopted, in order to understand the chance of a specific source of information…
Role of dioxygenase α-DOX2 and SA in basal response and in hexanoic acid-induced resistance of tomato (Solanum lycopersicum) plants against Botrytis …
2015
Resistance of tomato (Solanum Lycopersicum) to the fungal pathogen Botrytis cinerea requires complex interplay between hormonal signalling. In this study, we explored the involvement of new oxylipins in the tomato basal and induced response to this necrotroph through the functional analysis of the tomato α-dioxygenase2 (α-DOX2)-deficient mutant divaricata. We also investigated the role of SA in the defence response against this necrotrophic fungus using SA-deficient tomato nahG plants. The plants lacking dioxigenase α-DOX2, which catalyses oxylipins production from fatty acids, were more susceptible to Botrytis, and hexanoic acid-induced resistance (Hx-IR) was impaired; hence α-DOX2 is requ…
Evolutionary priming and transition to the ectomycorrhizal habit in an iconic lineage of mushroom-forming fungi: is preadaptation a requirement?
2021
AbstractThe ectomycorrhizal symbiosis is an essential guild of many forested ecosystems and has a dynamic evolutionary history across kingdom Fungi, having independently evolved from diverse types of saprotrophic ancestors. In this study, we seek to identify genomic features of the transition to the ectomycorrhizal habit within the Russulaceae, one of the most diverse lineages of ectomycorrhizal fungi. We present comparative analyses of the pangenome and gene repertoires of 21 species across the order Russulales, including a closely related saprotrophic member of Russulaceae. The ectomycorrhizal Russulaceae is inferred to have originated around the Cretaceous-Paleogene extinction event (73.…
Characterizing and Quantifying Frustration in Quantum Many-Body Systems
2011
We present a general scheme for the study of frustration in quantum systems. We introduce a universal measure of frustration for arbitrary quantum systems and we relate it to a class of entanglement monotones via an exact inequality. If all the (pure) ground states of a given Hamiltonian saturate the inequality, then the system is said to be inequality saturating. We introduce sufficient conditions for a quantum spin system to be inequality saturating and confirm them with extensive numerical tests. These conditions provide a generalization to the quantum domain of the Toulouse criteria for classical frustration-free systems. The models satisfying these conditions can be reasonably identifi…
