For deployment in building it could be a problem to repeat only three channels. In this paper we compare standard three channel scheme (channels 1, 6 and 11) with four channel schemes. The most promising scheme is with channels 1, 5, 9 and 13, which involves overlapping channels, but the overlap is minimal and in certain distances (power levels) is possible to use this scheme. The problem could be in some countries which do not allow usage of 13 channels. We also compare other schemes, with overlapping channels, but they have a much lower throughput than scheme with channels 1, 5, 9 and 13.

The set of analysed enterprises was composed of 182 SMEs operating in the Region of South Moravia in the Czech Republic, which were active in R & D in 2012 and 2013. There were evaluated public sources of funding for innovation activities and selected financial ratios of economic performance. The hypotheses about the relationship between the amount of public support and profitability of enterprises were set up and statistically tested. The analysis proved sufficient level of profitability and liquidity of the SMEs involved in research, the worst economic performance of the smallest enterprises and the direct positive relationship between the amount of public support and the profitability in two size groups of enterprises, which refers to the positive impact of the public support on the economic performance of SMEs.

Research among consumers was conducted in each district of Vysočina Region (Jihlava, Žďár nad Sázavou, Třebíč, Havlíčkův Brod and Pelhřimov) by interviewing a sample of 819 respondents, selected by quota sampling methods. The research was aimed at analysing the ability of respondents to recognise and differentiate two existing regional labels VYSOČINA Regional Product®, Regional Food Vysočina Region and also nonexistent brand From Our Region Vysočina, created by authors. Data have been processed with correspondence analysis and showed that respondents connect different characteristics with the labels. Media analysis of the Vysočina regional labels revealed that media may help building awareness about the labels but they do not shape respondents' views on them. Examining the link between the frequency of different types of information in media and their potential impact on the labels' pereception by consumers have shown distorted image. Stronger consensus between research and media analysis have been examined only on importance of products' origin, which can be viewed as a logical inference from the name of the labels.

This paper aims to find main differences between insolvency proceedings in the countries of Visegrad four. The main goal is to describe insolvency law in member countries and then to compare it from the poin of view of main actors. This comparison can help to find which changes and ideas could be applied to improve and make more effective the Czech insolvency system. The countries of Visegrad four was selected because of their common history and similar economic development. First of all, the legal background of insolvency proceedings which is possible for legal entities in these countries is examined. Then this paper deals with insolvency proceedings from the point of view of their participants - creditors, debtors and insolvency administrator. We have found that insolvency proceedings in these countries are very similar but there is still some inspiration for the Czech insolvency system.

This methodology assigns a score to each output according to a various categories. The evaluation is carried out for 5 year-long sliding period. However, the assigned score for an output is published with more than a year delay. Moreover, the assigned score, in most of the cases, does not correspond with the scientists' first calculation, which was made according to the generally known rules. The impact of this issue on the chosen scientific organisations, Higher Education Institutions (HEIs), is the topic of this paper. The evaluation and analysis of the financial impact of this gap on the Czech higher education institutions' budgets is provided with data from the years 2007 to 2012.

The main goal is to find and apply an efficient simulation model of pig breeding process in order to investigate the impact of various changes in the production settings on the economy of a particular pig breeding. For this reason, it is necessary to take values given in the study as model ones. Costs at particular parts of the breeding process were used as the main simulation inputs, together with number of parities, length of farrowing interval, number of weaned piglets depending on a parity number, lactation length, and the gestation length of sows. Additional inputs were price of produced piglets, price of insemination doses etc. Statistical distributions for the simulations of the inputs were obtained with theoretical curve fitting of sample data, which were provided from research projects focused on piglet production efficiency. The empirical distribution of sow profitability depending on the number of parities, which can help to decide about the culling of sows from the herd, was also determined in the research. A simulation was performed using the program @RISK. The obtained results and recommendations are discussed at the end of the paper.

These are those operations that are associated with the formation or dissolution of companies or reorganization of their ownership structure. They are often referred as equity transactions. In the concept of Czech accounting legislation, these are the purchase, sale, investment (deposit) of firms or their parts, and various forms of transformation of enterprises. There are analyzed the accounting practices of recording of these issues under the Czech accounting legislation and International Financial Reporting Standards. Consequently there are identified newly acquired assets and liabilities arising directly in connection with the business combinations. In the conclusion of this paper there are examined the effects of different reporting of newly acquired items in the context of business combinations according to Czech accounting legislation and in accordance with International Financial Reporting Standards on the significant items of balance sheet and profit and loss statement from the material and time point of view.

Churchilla 4, 130 67 Praha 3, Czech Republic Title: Disclosure of Subsidiaries with Non-controlling Interest in Accordance with IFRS 12: Case of Materiality Abstract: Consolidated financial statements present aggregated information for parent company and its subsidiaries. For non-wholly owned subsidiaries, International Financial Reporting Standards require non-controlling interest to be presented within consolidated equity to distinguish it from the amount of equity attributable to the shareholders of the parent. Since 2014, new standards on consolidation introduced broadened disclosure requirements for subsidiaries with material non-controlling interest. Definition of material non-controlling interest however is not included in the standards. The article provides the analysis of the financial statements published by companies listed on Prague Stock Exchange. Main focus is given to assessment criteria applied to identify material non-controlling interest. Consequently, study of compliance with the disclosure requirements for selected companies has been undertaken. The results of the analysis indicate whether value relevance of financial statements has been improved as a result of the new disclosures.

Abstract: There is no doubt about the existence of connection between the stock markets and the real economic activity. Many researchers indicated that the stock markets causally affect the economic activity with the lag of three months. Contrary, the other group of researchers suggested, that these relationships are reversal, moreover some of them concluded that these relationships are reciprocal. The paper analyses the relationship between the stock markets and the economic activity in seven countries with the research objective to identify these relationships in relation of cause and effect. As the proxy of the stock markets are stock indices considered, while the economic activity is expressed by the Gross Domestic Product at constant prices. The correlation analysis and the Granger causality test applied on suggested vector autoregressive models are employed for the research in the paper. The paper concludes that stock markets may be considered as the significant predictor of the real economic activity with the lag of one quarter, however, there is no reciprocal links between them.

Low production could be also caused by less intensive use of machinery. Aerial parts could be fully harvested by mechanisation, but in case of small growers using of special machinery is not economic. The majority of growers harvest manually and this type of harvest represents up to 80% of the costs associated with the cultivation. The less expensive alternative of harvest by a hedge trimmer is evaluated in this article. The goal is to compare two ways of harvest (manual harvest and hedge trimmer harvest) of lemon balm aerial parts in production practise. According to results of experiments were calculated and determined boundaries of effective use of hedge trimmer in production of lemon balm in comparision to manual harvest and fully mechanised harvest. Obtained data shown an increase of harvest performance in case of hedge trimmer (0.0425-0.0525 ha.hr-1) compared to manual harvest (0.0185-0.0216 ha.hr-1). According to calculations, we can say that effective use of hedge trimmer (including purchase price) is from 0.37 ha at planting surface and 0.48 ha at planting rows. Results could also be used for other MAP crops with similar harvest technology as for lemon balm (for example Mentha spp., Origanum spp., Achillea spp.).

This is also thanks to discoveries of enormous mineral wealth. Copper, coal, iron ore and gold in particular are responsible for an amazing growth performance that Mongolia continues to demonstrate over the last decade. As literature demonstrates, large windfalls in natural resources revenues often turn into a curse in the long run, inspiring the term 'resource curse'. Resource abundant countries are often confronted with negative economic, social and political outcomes. Poor management of resource revenues is often the core of this problem.The article looks at the case of Mongolia. It runs eight tests related to competitiveness, to quality of institutions, to GDP and to growth rate determined by global mineral prices. The results are mixed: tests of institutional quality and volatility of prices has proved the hypothesis, however, the GDP growth and terms of trade tests haven't shown any negative influence.The results offer a mixed picture (6 tests supporting and 2 tests not-supporting the hypothesis). At this stage, in overall, Mongolia is not yet facing the resource curse. Policy recommendations concern much needed stabilisation of the economy, improvement of institutional quality through legal reforms, and diversification of the economy.

There are many studies, articles and methodological guidebooks available describing proper design principles for technical parameters of underpasses and their placement within the terrain. Width, height and length are the main technical parameters affecting wildlife migration. Wildlife behaviour and their requirements for the mentioned technical parameters of underpasses also have been examined in depth. In practically all cases, underpass functionality grows with increasing width and height. Of course, this also results in greater construction costs. The objective should therefore be to find a balanced compromise enabling "sufficient" functionality while maintaining "reasonable" costs. Data envelopment analysis (DEA) provides a way to identify "good" solutions in the sense of "sufficient" underpass functionality with "reasonable" total costs. Underpass functionality calculations were based on a methodology for calculating migration potentials (Žák and Florian, 2013). Total costs were established according to actual construction work prices in the Czech Republic, including prices for preparations, design, construction, maintenance, and demolition. The results indicate that DEA can be used to find "good" solutions and can be of assistance in particular when planning measures to ensure motorways are permeable to wildlife.

This is due to the fact that oil as a commodity plays a central role in the economic activities of the nation. The objective of this paper is to investigate the dynamic relationship between oil price shocks and macroeconomic variables in the Ghanaian economy. This is achieved through the use of Vector Autoregressive (VAR) and Vector Error Correction (VECM) models. The variables considered in the study include: real oil price, real government expenditure, real industry value added, real imports, inflation and the real effective exchange rate. The study points out the asymmetric effects of oil price shocks; for instance, positive as well as negative oil price shocks on the macroeconomic variables used. The empirical findings of this study suggest that both linear and nonlinear oil price shocks have adverse impact on macroeconomic variables in Ghana. Positive oil price shocks are stronger than negative shocks with respect to government expenditure, inflation and the real effective exchange rate. Industry value added and imports have stronger responses to negative oil price shocks. Positive oil price shocks account for about 30% of fluctuations in government expenditure, 5% of imports, 6% of industry value added, 17% of inflation and 2% of the real effective exchange rate in the long run. Negative oil price shocks account for about 8% of fluctuations in government spending, 20% of imports, 8% of inflation and 2% of the real effective exchange rate in the long run. The data was obtained from the United States Energy Information Administration and the World Bank's World Development Indicators.

The study applied Hubbert's model of oil production and depletion. There was however modification to the approach in that Nonlinear Least Squares were used to estimate the logistic growth parameter instead of linear regression techniques. The modification was due to the fact that the historical data of oil production in Ghana did not follow a linear trend. The study acknowledges the influence of technology, economic, and political factors in the shorter time scales but hypothesizes that the amount of recoverable oil resources dominates all other factors in the long run. Hence the focus was placed on physical or geological constraints. The study results show that peak production in Ghana will occur in 2022. A maximum of about 100 million barrels will be produced per year though currently the annual production is about 40 million barrels. The predicted logistic curve also shows that total oil will be depleted by 2060. Ghana has total recoverable oil resources of about 1.8 billion. The data for the study was obtained from the U.S Energy Information Administration covers the period of production from 1992 to 2014.

The source of data for enterprises analysis was the firms database, which contains accounting data of 926 farms with at least one employee. The observed data were from the 6 year period (2007-2012). The farms were divided, according to their size into four categories defined by the European Commission: micro, small, medium and large enterprises. The analysis of the labour productivity I based on the added value and labour costs revealed that there are big differences of the labour productivity levels in particular size groups of farms. The further analysis revealed that an adjustment of the farm approach of the labour productivity, when the paid operation subsidies are added (labour productivity II), changes this conclusion and the differences between particular size groups of farms decreased. Using σ-convergence, it was proved that the relative variability of the labour productivity II values decreased significantly in the case of the medium-sized farms. We can say that subsidies significantly influence the labour productivity in farms. On one hand, there is decrease of differences between the level values of particular size groups of farms; on the other hand, there is no significant decrease its variability (except the medium-sized farms).

The method used in this study was practical in terms of objectives and descriptive-correlational in terms of data collection. In this study, the statistical population consisted of all the managers of different parts of Bushehr University of Medical Sciences and Medical Services including 257 individuals. Among these individuals, 149 persons were chosen as the sample size using the Morgan table and the Simple Random Sampling Method. In order to collect the data, a researcher-made questionnaire with 21 questions was used including the questionnaires of Morgan (2011), Ramprest and Hubert (2008) and Mohammadi Zanjirani (2012) for competencies of human resources and it also included a researcher-made questionnaire of the managers' performance with 30 questions based on the Keykhan Nezhad pattern (2008). The Cronbach's alpha method was used for the final assessment which the values were 0.74 for the first questionnaire and 0.81 for the second one. The content validity test was also utilized to check the validity so that the questionnaires were approved by the related experts. Analyzing the collected information from the questionnaire was performed by using SPSS software in two parts of Descriptive and Inferential (Kolmogorov-Smirnov test, the Pearson correlative test, and the multiple regressions). The results indicated that there was a positive and significant relationship between the two structures of human resources competencies and performance of the managers of human resources. Moreover, the relationship between all the dimensions of competencies (knowledge, attitude, skill and characteristic) and performance of the managers of human resources was significant.

This commodity is used in carousel fraud. In the chains of taxpayers there are missing traders who fail to meet their tax obligations. Their business strategy is based on quick sales at unusually low prices which do not allow honest parties to compete. Tax administrators should focus on unusual prices which constitute a higher probability of tax evasions. This paper aims to verify whether or not there are ways to evade the measure, focusing specifically on applying methods which could help achieve lower sales prices while avoiding the possibility to require unpaid tax from the recipients of taxable supply. The weaknesses thus found are described and demonstrated in more detail in the paper. During a research some ways were found which could be used for avoiding this specific measure. Methods of Cash Back and Free Shipping were identified and described.
