Acta Univ. Agric. Silvic. Mendelianae Brun. 2015, 63(1), 45-48 | DOI: 10.11118/actaun201563010045
While high surface smoothness of particleboards is usually desired, boards with expressed surface topology can be seen as a more recent development. This research is about the development of 3D-imprinted surface patterns applied to both sides of single-layer particleboards. The imprintment was done as a post-treatment, meaning it was carried out as a final processing step during particleboard production. Commercial particleboard samples were imprinted using a hexagonal steel pattern under high pressure. Results show that because of the imprinting bending strength and stiffness were both reduced by 2/3 to 3/4 of the compared control values. Even with...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2015, 63(1), 193-200 | DOI: 10.11118/actaun201563010193
IPO (Initial Public Offering) is a complex decision making task which is always associated with different types of uncertainty. Poor accuracies of available probabilities of lotteries e.g. quantification of investor interest is studied in the first part of this paper (Meluzín, Doubravský, Dohnal, 2012). However, IPO is often prohibitively ill-known. This paper takes into consideration the fact that decision makers cannot specify the structure/topology of the relevant decision tree. It means that one IPO task is specified by several (partially) different decision trees which comes from different sources e.g. from different teams of decision makers/experts....

Acta Univ. Agric. Silvic. Mendelianae Brun. 2015, 63(1), 235-243 | DOI: 10.11118/actaun201563010235
The main aim of this article is to develop a new model supporting the identification of the particular corporate life stage within the corporate life cycle. This model will be derived from the Boston matrix. The main reason for using this approach as the base for making new model of the corporate life cycle is the fact, that every quadrant of the Boston matrix can be assigned to one phase of the product life cycle and there is supposed, that the phase, in which are most products, determines the phase of the corporate life cycle. For application the Boston matrix by identification phases of the corporate life cycle is necessary to define low and high...

Investment decisions are at the core of any development strategy. Economic growth and welfare depend on productive capital, infrastructure, human capital, knowledge, total factor productivity and the quality of institutions. Decision-making process on the selection of suitable projects in the public sector is in some aspects more difficult than in the private sector. Evaluating projects on the basis of their financial profitability, where the basic parameter is the value of the potential profit, can be misleading in these cases. One of the basic objectives of the allocation of public resources is respecting of the 3E principle (Economy, Effectiveness,...

The approach to working capital management significantly affects the performance of companies. Nevertheless, this effect varies depending on the observed industry and company's size and it may be assumed that it is also dependent on territory differences. The paper presents an empirical research aiming to identify particular links between net working capital and costs of the company. The outcomes indicate a relatively strong positive correlation between the variables, especially in case of inventory. Furthermore he ratio of financial costs to ordinary costs is low, as well as the impact of net working capital components on financial costs. It follows...
