František Gregor, Hana Šefrová, Zdeněk Laštůvka
Acta Univ. Agric. Silvic. Mendelianae Brun. 2017, 65(3), 833-838 | DOI: 10.11118/actaun201765030833
Individual variability of wing patterns is not frequent in European species of the genus Phyllonorycter Hübner, 1822. It is unusually distinct in Phyllonorycter salictella (Zeller, 1846) which causes some taxonomic ambiguities and oversights. We found on numerous material of adults reared from overwintering pupae collected in the Czech and Slovak Republics since 1950 that this variability is related with altitude (temperature). Adults with the distinct generotypic (plesiomorphic) wing patterns dominated in submountain populations while individuals with the strongly reduced (apomorphic) wing drawings were represented quite negligibly....

Sowing is affected by numerous factors, and thus high-quality sowing is a very important task for agricultural engineers and managers of profitable agricultural production. The primary purpose of sowing is placing seeds at proper depths and in-row spacings in well-prepared soil. Plant population particularly gives prominence to sowing as it directly affects the uniformity of plant growth and development. Soybean planting is especially dependent on the quality of planting for yield formation due to the significant vicinity of seeds. Provided all external factors of high-quality sowing are met, i.e. sowing conditions, the quality of sowing depends upon...
Abstract Modelling of the Impact of Activities of Economic Entities on the Social System
Dana Bernardová, Eva Jílková, Miroslav Pokorný, Zdeňka Krišová
Acta Univ. Agric. Silvic. Mendelianae Brun. 2017, 65(3), 965-976 | DOI: 10.11118/actaun201765030965
Economic entities as integral parts of the social system have an impact on it. The complexity of structures and uncertainty of behaviour which are also conditioned by incorporating the human factor are the typical characteristics of economic entities and the social system. The lack of precise measurement data as well as precise information is their typical feature. Methods of creating computer models of such systems must therefore be based on uncertain, incomplete or approximate data and hypothetical assumptions. The paper deals with the synthesis of the abstract model of the expert system for determining the level of corporate social responsibility...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2017, 65(3), 1015-1022 | DOI: 10.11118/actaun201765031015
According to the Basel Committee's estimate, three quarters of counterparty credit risk losses during the financial crisis in 2008 originate from credit valuation adjustment's losses and not from actual defaults. Therefore, from 2015, the Third Basel Accord (EU, 2013a) and (EU, 2013b) instructed banks to calculate the capital requirement for the risk of credit valuation adjustment (CVA). Banks are trying to model CVA to hold the prescribed standards and also reach the lowest possible impact on their profit. In this paper, we try to model CVA using methods that are in compliance with the prescribed standards and also achieve the smallest possible impact...

Hoang Duong Vu, Van Hung Le
Acta Univ. Agric. Silvic. Mendelianae Brun. 2017, 65(3), 1075-1084 | DOI: 10.11118/actaun201765031075
This study empirically examines relationship between FDI spill-overs and technical efficiency of domestic firms and role of the absorptive capacity of domestic firms. Data on Vietnamese Annual Enterprises Survey are exploited to build a firm-level panel data on the Vietnamese wearing apparel industry from 2009 to 2013. By applying stochastic production frontier model, this paper shows that there are positive vertical spill-over effects but no horizontal effects. Moreover, this study finds the negative impact of the absorptive capacity of domestic firms on benefits reaped from FDI externalities.

Acta Univ. Agric. Silvic. Mendelianae Brun. 2017, 65(3), 1085-1098 | DOI: 10.11118/actaun201765031085
On the one hand, tourism is a significantly spatially differentiated socio-economic phenomenon, bound to the attractiveness of local conditions. On the other hand, it is a sectional phenomenon which requires a high level of coordination and cooperation of all tourism stakeholders. This is the background for the practical implementation of tourism policy. The state's conceptual activity and its institutions are irreplaceable in this respect. From this point of view, a prerequisite for quality economic-political decisions of the existence of materials and methods, which these features respect, is necessary. One of these prerequisites is a quantitative...
