Cross-scale impact of climate temporal variability on ecosystem water and carbon fluxes
Get PDFWhile the importance of ecosystem functioning is undisputed in the context of climate change and Earth system modeling, the role of short-scale temporal variability of hydrometeorological forcing (~1?h) on the related ecosystem processes remains to be fully understood. Various impacts of meteorological forcing variability on water and carbon fluxes across a range of scales are explored here using numerical simulations. Synthetic meteorological drivers that highlight dynamic features of the short temporal scale in series of precipitation, temperature, and radiation are constructed. These drivers force a mechanistic ecohydrological model that propagates information content into the dynamics of water and carbon fluxes for an ensemble of representative ecosystems. The focus of the analysis is on a cross-scale effect of the short-scale forcing variability on the modeled evapotranspiration and ecosystem carbon assimilation. Interannual variability of water and carbon fluxes is emphasized in the analysis. The main study inferences are summarized as follows: (a) short-scale variability of meteorological input does affect water and carbon fluxes across a wide range of time scales, spanning from the hourly to the annual and longer scales; (b) different ecosystems respond to the various characteristics of the short-scale variability of the climate forcing in various ways, depending on dominant factors limiting system productivity; (c) whenever short-scale variability of meteorological forcing influences primarily fast processes such as photosynthesis, its impact on the slow-scale variability of water and carbon fluxes is small; and (d) whenever short-scale variability of the meteorological forcing impacts slow processes such as movement and storage of water in the soil, the effects of the variability can propagate to annual and longer time scales
Asyndetic Compound Sentences in Valeriy Shevchuk’s Fiction Stylistics
No full textУ статті висвітлено формально-граматичні, стилістичні та контекстуальні особливості складних безсполучникових речень, що функціонують у творах В. Шевчука, визначено диференційні ознаки стилістичного синтаксису мови письменника. The article analyzes the grammatical, stylistic and contextual peculiarities of asyndetic sentences in Valeriy Shevchuk’s fiction. Stylistic meaning of asyndetic sentences differs from comlex and compound sentences. Asyndetic sentences give dynamics and expressiveness to the fiction. Asyndetic form speeds up the rhythm of the narration. In Valeriy Shevchuck’s novels the compound asyndetic sentences convey/verbalize the sequence and the simultaneousness of actions. The author uses the compound asyndetic sentences to describe nature, characters, events and occurrences. The compound asyndetic sentences create an oral style
"Could you speak up?" [David Coombe, Valery Ivanov, Bob Hawke] [picture] /
No full textTitle devised by cataloguer.; Published in the Canberra Times on 10 July 1983.; Part of the Pryor collection of cartoons and drawings. The Sunday roundup. The big story of the week is the release by the Hope Royal Commission into Australian Security of transcripts of bugged conversations between former ALP National Secretary David Combe and Soviet Diplomat Valeriy Ivanov. Sections of the transcripts are frustratingly labelled 'inaudible' while the conversations seem, at the same time, to be well lubricated
Replication Data for: Fundamentally New Methods for Transformation of the Value of Commodities into Original and Equilibrium Production Prices Using Marx's Five-Sphere Tables from Volume 3 of Capital
No full textAbstract
In this paper, the author presents fundamentally new methods for transforming the value of commodities into original and equilibrium prices of production using Karl Marx's five-sector tables from the third volume of Capital. Mathematical verification of methods is performed using sequential iterations and the program Wolfram Mathematics. For the first time, the method of inverse transformation of production prices of commodities into value prices is presented. It is proved that the pricing systems based on the principles of value and price of production are not mutually exclusive. They complement each other, representing a single whole. A comprehensive solution to the transformation problem shows that Karl Marx does not have the mistakes attributed to him by critics.

Abiotic and biotic controls of soil moisture spatio-temporal variability and the occurrence of hysteresis
Get PDFAn expression that separates biotic and abiotic controls on the temporal dynamics of the soil moisture spatial coefficient of variation Cv(?) was explored via numerical simulations using a mechanistic ecohydrological model, Tethys-Chloris. Continuous soil moisture spatiotemporal dynamics at an exemplary hillslope domain were computed for six case studies characterized by different climate and vegetation cover and for three configurations of soil properties. It was shown that abiotic controls largely exceed their biotic counterparts in wet climates. Biotic controls on Cv(?) were found to be more pronounced in Mediterranean climates. The relation between Cv(?) and spatial mean soil moisture inline image was found to be unique in wet locations, regardless of the soil properties. For the case of homogeneous soil texture, hysteretic cycles between Cv(?) and inline image were observed in all Mediterranean climate locations considered here and to a lesser extent in a deciduous temperate forest. Heterogeneity in soil properties increased Cv(?) to values commensurate with field observations and weakened signatures of hysteresis at all of the studied locations. This finding highlights the role of site-specific heterogeneities in hiding or even eliminating the signature of climatic and biotic controls on Cv(?), thereby offering a new perspective on causes of confounding results reported across field experiments
THE INFLUENCE OF INSTITUTIONAL CHANGES ON THE INVESTMENT ATTRACTIVENESS OF THE AGRICULTURAL SECTOR OF UKRAINIAN ECONOMY
No full textSuccessful development of the Ukrainian economy, its agro-industrial segment requires a large-scale and efficient investment provision and favourable investment climate. In this regard, the actual task of the scientific community is the study of the influence of institutions on the development of investment policy, the formation of investment processes in the country. The purpose of this article is the study of institutional basis for further development of the investment processes in the agricultural sector of Ukrainian economy under conditions of integration into Europe. In the study process author used general scientific methods, in particular statistical method, method of extrapolation, analogy, institutional analysis, abstract-logical method, methods of descriptive simulation. Results of the study are as follows. The influence of formal institutions (legal regulations for the ‘rules of play’) was assessed on the investment efficiency. The ponderability of the formal institutions was identified in the investment success of the big agricultural business of Ukraine. The main causes of the low investment attractiveness of small and medium-sized business in the agrarian sector of the Ukrainian economy were defined. The ways were substantiated for development of the non-formal institutions. It was accentuated that asset capitalization of the small and medium-sized companies would be important for development of the investment processes in Ukraine
Uncertainty partition challenges the predictability of vital details of climate change
No full textDecision makers and consultants are particularly interested in “detailed” information on future climate to prepare adaptation strategies and adjust design criteria. Projections of future climate at local spatial scales and fine temporal resolutions are subject to the same uncertainties as those at the global scale but the partition among uncertainty sources (emission scenarios, climate models, and internal climate variability) remains largely unquantified. At the local scale the uncertainty of the mean and extremes of precipitation is shown to be irreducible for mid and end-of-century projections because it is almost entirely due to internal climate variability (stochasticity). Conversely, projected changes in mean air temperature and other meteorological variables can be largely constrained, even at local scales, if more accurate emission scenarios can be developed. The results were obtained by applying a comprehensive stochastic downscaling technique to climate model outputs for three exemplary locations. In contrast with earlier studies, the three sources of uncertainty are considered as dependent and, therefore, non-additive. The evidence of the predominant role of internal climate variability leaves little room for uncertainty reduction in precipitation projections; however, the inference is not necessarily negative, since the uncertainty of historic observations is almost as large as that for future projections with direct implications for climate change adaptation measures
Systemic Features of Living Before and After Human
No full textThroughout history, man has tried unsuccessfully to understand his own nature. The main reason was the lack of a conceptual apparatus of a higher level than his own consciousness. Systemic methodology is capable of compensating for this inadequacy. It allows one to build systemic models of living beings past and future phylogenetic stages. This ensures the possibility of correctly assessing his systemic resources at present and in the future. This knowledge is necessary in all spheres of human activity.
