    Entrepreneurship as a potential driving force for the further development of rural areas

    Entrepreneurial human capital and entrepreneurship are crucial elements for the further develop - ment of rural areas. In order to understand the role of rural enterprises it is essential to learn the characte - ristics of successful companies in local economies. The main aim of this paper is to demonstrate through the introduction of the activity, everyday practice and production procedure how non-agricultural and non-tourism enterprises can foster the development of rural and peripheral areas in the Visegrad countries. Nine local enter - prises of different size, profile and development pathway were examined in order to highlight main experiences and lessons being vital for and adaptable in other disadvantaged areas. The results and company descriptions provided in the article are based on in-depth interviews, online data collection and statistical analys

    The Syntax of givenness

    Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Linguistics and Philosophy, 2007.Includes bibliographical references (p. 193-208).The goal of this thesis is to account for distributional patterns of given and new items in Czech, especially their word order. The system proposed here has four basic components: (i) syntax, (ii) economy, (iii) interpretation, and (iv) reference set computation. The approach belongs to the family of interface driven approaches. The syntactic part of the thesis introduces a free syntactic movement (G-movement). The movement causes very local reordering of given elements with respect to new elements in the structure. G-movement is licensed only if it creates a syntactic structure which leads to a semantic interpretation that would not otherwise be available. The economy condition interacts with the way givenness is interpreted. I introduce a recursive operator that adds a presupposition to given elements. The distribution of the operator is regulated by the Maximize presupposition maxim of Heim (1991). The reference set for purposes of this evaluation is defined as the set of derivations that have the same numeration and the same assertion. Finally, I argue that the licensing semantic conditions on givenness in Czech are not identical to the licensing conditions on deaccenting in English. The givenness licensing conditions are stronger in that they require that for an element to be given it must not only have a salient antecedent but also satisfy an existential presupposition.by Ivona Kučerová.Ph.D

    Time-dependent spectral-feature variations of stars displaying the B[e] phenomenon; I. V2028 Cyg

    Full text link
    We present results of nearly six years of spectroscopic observations of the B[e] star V2028 Cyg. The presence of the cold-type absorption lines combined with a hot-type spectrum indicate the binarity of this object. Since B[e] stars are embedded in an extended envelope, the usage of common stellar atmosphere models for the analysis is quite inappropriate. Therefore, we focus on the analysis of the long-term spectral line variations in order to determine the nature of this object. We present the time dependences of the equivalent width and radial velocities of the H alpha line, [O I] 6300 A, Fe II 6427, 6433, and 6456 A lines. The bisector variations and line intensities are shown for the H alpha line. The radial velocities are also measured for the absorption lines of the K component. No periodic variation is found. The observed data show correlations between the measured quantities, which can be used in future modelling

    Microstructural enrichment functions based on stochastic Wang tilings

    Full text link
    This paper presents an approach to constructing microstructural enrichment functions to local fields in non-periodic heterogeneous materials with applications in Partition of Unity and Hybrid Finite Element schemes. It is based on a concept of aperiodic tilings by the Wang tiles, designed to produce microstructures morphologically similar to original media and enrichment functions that satisfy the underlying governing equations. An appealing feature of this approach is that the enrichment functions are defined only on a small set of square tiles and extended to larger domains by an inexpensive stochastic tiling algorithm in a non-periodic manner. Feasibility of the proposed methodology is demonstrated on constructions of stress enrichment functions for two-dimensional mono-disperse particulate media.Comment: 27 pages, 12 figures; v2: completely re-written after the first revie

    New vs. Given

    Get PDF
    This squib begins with an argument emphasizing that the grammar of English makes a distinction between constituents that are focused and those that are merely new, hence not given. If the distinction is made via features, we need two features: one indicating focus and one indicating either given or new information. Which one of the two? Semantically, the choice doesn’t matter: whatever information is given is not new and the other way round. For the phonology, there is a difference, however. If the prosody of all-new constituents is default prosody, but the prosody of given constituents is special, we would want to indicate givenness, rather than newness

    Another building block in the plant cell wall: Barley xyloglucan xyloglucosyl transferases link covalently xyloglucan and anionic oligosaccharides derived from pectin

    Published online 16 August 2020.We report on the homo‐ and hetero‐transglycosylation activities of the HvXET3 and HvXET4 xyloglucan xyloglucosyl transferases (XET; EC 2.4.1.207) from barley (Hordeum vulgare L.), and the visualisation of these activities in young barley roots using Alexa Fluor 488‐labelled oligosaccharides. We discover that these isozymes catalyse the transglycosylation reactions with the chemically defined donor and acceptor substrates, specifically with the xyloglucan donor and the penta‐galacturonide [α(1‐4)GalAp]5 acceptor – the homogalacturonan (pectin) fragment. This activity is supported by 3D molecular models of HvXET3 and HvXET4 with the docked XXXG donor and [α(1‐4)GalAp]5 acceptor substrates at the ‐4 to +5 subsites in the active sites. Comparative sequence analyses of barley isoforms and seed‐localised TmXET6.3 from nasturtium (Tropaeolum majus L.) permitted the engineering of mutants of TmXET6.3 that could catalyse the hetero‐transglycosylation reaction with the xyloglucan/[α(1‐4)GalAp]5 substrate pair, while wild‐type TmXET6.3 lacked this activity. Expression data obtained by real‐time quantitative PCR of HvXET transcripts and a clustered heatmap of expression profiles of the gene family revealed that HvXET3 and HvXET6 co‐expressed but did not share the monophyletic origin. Conversely, HvXET3 and HvXET4 shared this relationship, when we examined the evolutionary history of 419 glycoside hydrolase 16 family members, spanning monocots, eudicots, and a basal Angiosperm. The discovered hetero‐transglycosylation activity in HvXET3 and HvXET4 with the xyloglucan/[α(1‐4)GalAp]5 substrate pair is discussed against the background of roles of xyloglucan‐pectin heteropolymers and how they may participate in spatial patterns of cell wall formation and re‐modelling, and affect the structural features of walls.Barbora Stratilová, Sergej Šesták, Jozef Mravec, Soňa Garajová, Zuzana Pakanová, Kristína Vadinová, Danica Kučerová, Stanislav Kozmon, Julian G.

    Advances in Formal Slavic Linguistics 2016 initiates a new series of collective volumes on formal Slavic linguistics. It presents a selection of high quality papers authored by young and senior linguists from around the world and contains both empirically oriented work, underpinned by up-to-date experimental methods, as well as more theoretically grounded contributions. The volume covers all major linguistic areas, including morphosyntax, semantics, pragmatics, phonology, and their mutual interfaces. The particular topics discussed include argument structure, word order, case, agreement, tense, aspect, clausal left periphery, or segmental phonology. The topical breadth and analytical depth of the contributions reflect the vitality of the field of formal Slavic linguistics and prove its relevance to the global linguistic endeavour. Early versions of the papers included in this volume were presented at the conference on Formal Description of Slavic Languages 12 or at the satellite Workshop on Formal and Experimental Semantics and Pragmatics, which were held on December 7-10, 2016 in Berlin
