Complex risks from old urban waste landfills – a sustainability perspective from Iasi, Romania
Landfills continue to represent the most frequent managerial practice for municipal solid wastes and an increasing and complex problem globally. In certain countries, a transition to an open society and free market is superimposed on the transition to sustainability, resulting in even higher complexity of management. This paper proposes an approach for problem-structuring of landfills in complex transitions: sustainability or unsustainability of

Climate change and resource shortages will force us to transform our economy and society. If we do not break out of the old, unsustainable techno-economic paradigm of the 20th century1, a perfect storm2 looms within decades. Experts from virtually all sectors are now talking about the need for innovation to transform whole industries, ensuring industrial leadership and a leap towards “sustainable growth” in Europe. Now is not the time to cut
Read moreDynamic decision trees for building resilience into future eco-cities
Intensifying global urbanization and environmental changes bring about the imperative of sustainable urban development and decisions upon inescapable pressures and risks, but knowledge integration between disciplines is a limiting contextual challenge. This paper proposes a reformulation, in terms of urban risk management, of an earlier developed ontological scenario generation method. The procedure consists of several steps: (i) identification-and-prioritization

We present temperature dependent magnetic neutron diffraction measurements on Ba(Fe1−xCox)2As2 for x=0.039, 0.022, and 0.021 as-grown single crystals. Our investigations probe the behavior near the magnetic tricritical point in the (x,T) plane, xtr≈0.022, as well as systematically exploring the character of the magnetic phase transition across a range of doping values. All samples show long-range antiferromagnetic order that may be described
Read moreEffect of electron correlations on the spin excitations in isovalently doped iron based superconductor Ba(Fe1-xRux)2As2
Magnetic correlations in isovalently doped Ba(Fe1-xRux)2As2 (x=0.25, Tc=14.5 K; x=0.35, Tc=20 K) are studied by elastic and inelastic neutron scattering techniques. A relatively large superconducting spin gap accompanied by a weak resonance mode is observed in the superconducting state in both samples. In the normal state, the magnetic excitation intensity is dramatically reduced with increasing Ru doping toward the optimally doped regime.

The authors analyzed by transmission electron microscopy (TEM) neurosurgical samples obtained from patients with cerebral tumors, neurotrauma, cerebral ischemia, Moyamoya disease, encephalitis, etc. Their observations concern a variety of dying cell types by different programmed death pathways, including apoptosis, paraptosis, autophagy, autoschizis, programmed necrosis, as well as combined and coexisting forms. This ample work pointed out not only
Read moreFinancial instability and ECB monetary policy
This paper proposes an assessment of the monetary policy performed by the European Central Bank (ECB) and, more specifically this paper investigates to what extent the ECB monetary policy decisions were guided by financial instability signals. Our assessment is achieved by estimating a Taylor’s rule, augmented by financial instability aggregate indicators. This estimate enables us, on the one hand, to compare the fitted model predictions against
Read moreFinancial stability, monetary policy and budgetary coordination in EMU
A series of recent studies analyze the impact of financial crisis on the fiscal soundness in the Euro area countries. Even if their documented results present the transmission mechanisms of the financial instability toward the fiscal sector, a more realistic problem is related to the contribution of the fiscal and budgetary disequilibrium to the financial instability propagation. In this line, we show, based on a simple econometric model that, beside
