Mitigation of agricultural diffuse pollution poses a significant policy challenge across Europe and particularly in the UK. Existing combined regulatory and voluntary approaches applied in the UK continue to fail to deliver the necessary environmental outcomes for a variety of reasons including failure to achieve high adoption rates. It is therefore logical to identify specific on-farm mitigation measures towards which farmers express positive attitudes for higher future uptake rates. Accordingly, a farmer attitudinal survey was undertaken during phase one of the Demonstration Test Catchment programme in England to understand those measures towards which surveyed farmers are most receptive to increasing implementation in the future. A total of 29 on-farm measures were shortlisted by this baseline farm survey. This shortlist comprised many low cost or cost-neutral measures suggesting that costs continue to represent a principal selection criterion for many farmers. The 29 measures were mapped onto relevant major farm types and input, assuming 95% uptake, to a national scale multi-pollutant modelling framework to predict the technically feasible impact on annual agricultural emissions to water and air, relative to business as usual. Simulated median emission reductions, relative to current practise, for water management catchments across England and Wales, were estimated to be in the order sediment (20%)>ammonia (16%)>total phosphorus (15%)>nitrate/methane (11%)>nitrous oxide (7%). The corresponding median annual total cost of the modelled scenario to farmers was £3 ha-1yr-1, with a corresponding range of -£84ha-1yr-1 (i.e. a net saving) to £33ha-1yr-1. The results suggest that those mitigation measures which surveyed farmers are most inclined to implement in the future would improve the environmental performance of agriculture in England and Wales at minimum to low cost per hectare. © 2015 Elsevier B.V.

The article concerns with a process of the air traffic controllers (ATCo) selection in the Czech Armed Forces. It describes current state of this process and balances it briefly against the civil sector and some NATO armies. The text comes out from the assumption that the air traffic control profession is the profession specific by its work content and workload and so it has special requirements on its candidates. The authors occupy themselves with the thought of how effective is the process of the air traffic controllers selection without testing the candidates’ aptitude to use simulation technologies. © 2015.

Current business environment in world perspective brings different impact on possible development. During economic crisis in last couple of years world economic growth has getting slower, market shares are rapidly falling down. That situation could create new dimension of competition because of large competitors' intensity on the market due to developed logistics and information technologies. Based on the theoretical data there are applied statistical methods, which should be achieved of main aim of the paper. The main aim of the article is defining possible trend of using business tools as a way, how is practicable get out of economic crisis. For this reason there was used questionnaire survey, focused on small and medium companies during economic crisis (between 2009 and 2013). Observed business tools have quite excellent usage not only in the time of crisis, but also in prosperity times, when the companies provide unique competitive advantages. During tracked periods there were advance of gained knowledge about compensation tools by various learning methods. © 2015, Mendel University of Agriculture and Forestry Brno. All rights reserved.

This article is focused on determination of the most significant economic indicators influencing corporate sustainability performance. Corporate sustainability performance is a multidimensional concept based on the original idea of sustainable development, replacing the traditional understanding of corporate performance only as capital appreciation for owners (shareholders). Compared to the original concept of sustainable development which consists of environmental, social and economic performance, the so-called triple-bottom-line, it is broaden to the responsibilities and the impact of Corporate Governance on the corporate performance. The basic set of economic indicators has been constructed from a synthesis of resources developed by international organizations (Global Reporting Initiative, International Federation of Accountants) and research among manufacturing companies in the Czech Republic. The basic set of twenty-five key indicators is divided into seven groups: Costs, Investments, Economic Results, Asset & financial resources utilization, Suppliers reliability, Penalties and R&D expenses. Basic set of indicators was presented to 23 top-managers who quantified the potential effect of each indicator to the success and sustainability of their companies. Through the methods of descriptive statistics knowledge of the particularities of each indicator was obtained. Correlation analysis and factor analysis were applied in order to eliminate information duplicity and dimensionality reduction. The result is a reduction in the number of economic indicators, so that the loss of information on the influence of the original indicators on the corporate sustainability is minimized. Corporate sustainability indicators are a tool for measuring and managing progress towards sustainability goals and environmental, social and economic impacts. © 2015 The Authors.

Measuring the time variations of Doppler frequencies and angles of arrival (AoA) of ionospherically reflected HF waves has been proposed as a means of detecting the occurrence of traveling ionospheric disturbances (TIDs). Simulations are made using ray tracing through the International Reference Ionosphere (IRI) electron density model in an effort to reproduce measured signatures. The TID is represented by a wavelike perturbation of the 3-D electron density traveling horizontally in the ionosphere with an amplitude that varies sinusoidally with time. By judiciously selecting the TID parameters the ray tracing simulation reproduces the observed Doppler frequencies and AoAs. Ray tracing in a 3-D realistic ionosphere is, however, excessively time consuming considering the involved homing procedures. It is shown that a carefully selected reflecting corrugated mirror can reproduce the time variations of the AoA and Doppler frequency. The results from the ray tracing through the IRI model ionosphere and the mirror model reflections are compared to assess the applicability of the mirror-reflection model. © 2016.
