On Determinants Of The Economic Growth Of European Countries During 2005–2015

The aim of the paper is to examine the economic growth of 32 European countries from 2005 to 2015. This period was characterized by a strong growth prior to 2009, when the Great Recession started, and lasted until 2012-2013 in the majority of examined countries. The growth between 2005 and 2015 was studied with regard to six selected socio-economic factors: initial level of the gross domestic product, economic openness, democracy index, human capital, physical capital, and foreign direct investments. The main result is that the growth was directly proportional to human and physical capital, and indirectly proportional to the initial level of GDP and the democracy index. Furthermore, cluster analysis showed that the historical division of Europe into “West” and “East” still persists to a considerable extent

Decision making under risk with continuous states of nature

Many real-world decision making situation are associated with uncertainty regarding future state of the World. Traditionally, in such situation different (and discrete) scenarios – future states of nature – are considered. This domain of decision making is denoted as decision making under risk. However, limitation to some set of discrete scenarios is somewhat unnatural as future reality might not choose one of considered scenarios, but some other scenario or a scenario in between. The aim of this paper is to propose a more natural approach with continuum states of nature, where all scenarios expressed by their probability density function from some reasonable interval are taken into consideration. The approach is illustrated by a numerical example and is compared with the corresponding decision making under risk with discrete states of nature

Land Use and Remedy Selection: Experience from the Field — The Abex Site

As the United States Congress debates revisions to the federal Superfund law, one of the most important topics of discussion is the degree to which cleanups at Superfund sites should be based on their expected future land use. This discussion has engaged the Superfund community for several years. Despite this apparent interest in linking cleanup with land use, however, surprisingly little analysis has been done on what role land use already plays in selecting remedies. RFF researchers have addressed the shortfall with case studies at three Superfund sites—Abex Corporation in Portsmouth, Virginia, Industri-Plex in Woburn, Massachusetts, and Fort Ord near Monterey, California—where land use has played a prominent role in the remedy selection process. Each of the case studies includes a description of: the contamination at the site; the different stakeholders involved in the remedy selection process; and the influence that land use considerations have had on this process. The three case studies are part of a larger RFF research project on land use and remedy selection that was funded in part under a grant from the U.S. Environmental Protection Agency.

The decay of quantum correlations between quantum dot spin qubits and the characteristics of its magnetic field dependence

We address the question of the role of quantum correlations beyond entanglement in context of quantum magnetometry. To this end, we study the evolution of the quantum discord, measured by the rescaled discord, of two electron-spin qubits interacting with an environment of nuclear spins via the hyperfine interaction. We have found that depending on the initial state the evolution can or cannot display indifferentiability points in its time-evolution (due to the energy conservation law), as well as non-trivial dependence on inter-qubit phase. Furthermore, we show that for initial Bell states, quantum correlations display a strong magnetic-field sensitivity which can be utilized for decoherence-driven measurements of the external magnetic field. The potential discord-based measurement is sensitive to a wider range of magnetic field values than the entanglement-based measurement. In principle, entanglement is not a necessary resource for reliable decoherence-driven measurement, while the presence of quantum correlations beyond entanglement is.Comment: 9 pages, 6 figure
