Hacia la convergencia de las estadísticas de las finanzas públicas y la contabilidad pública en Europa a nivel central y local
2018
[EN] The main aim of this paper is to study the convergence between micro and macro systems of government accounting information, looking to contribute to the analysis of accounting harmonization process in the EU, as a tool to improve the comparability of financial, budgetary, and aggregated statistical reports, in order to improve social, political and economic decision-making and accountability. All this is obviously located in the current context of the EU, with a high degree of harmonization of accounting standards between the International Public Sector Accounting Standards (IPSAS), and those applied for the preparation of national accounts, ruled by European System of National and Re…
Non absolutely convergent integrals of functions taking values in a locally convex space
2006
Properties of McShane and Kurzweil-Henstock integrable functions taking values in a locally convex space are considered and the relations with other integrals are studied. A convergence theorem for the Kurzweil-Henstock integral is given
Communicating with home, coping without home – Trusting to the mediating capacity of blogging
2021
Abstract In the early 21st century, blogs exploded onto the digital media scene and soon became a popular means of travel writing. However, rather than considering blogs as a straightforward tool to simply share stories and experiences, in this article, we set out to explore the role of blogs as a mediating technology (Verbeek, 2005a), especially during difficult times abroad. By analysing the blogs of expatriate Australians who were volunteers in Bangladesh in 2014/2015 as well as interviews with the bloggers, we are able to show how the blogs' affordances inform the coping process, highlighted, in particular, in an active and highly reflective engagement with the blog's unique situatednes…
Aproximación a la Geografía del despilfarro en España: balance de las últimas dos décadas
2018
Este trabajo pretende ser una primera aproximación a la dimensión del despilfarro de recursos públicos en infraestructuras en España desde 1995 hasta la actualidad en los distintos niveles de gobierno. A partir de algunas precisiones sobre los conceptos de despilfarro y corrupción, se analiza, de una parte, la inversión y los sobrecostes en infraestructuras innecesarias impulsadas y ejecutadas por la Administración General del Estado en el ámbito de sus competencias, y de otra, infraestructuras, proyectos, eventos e inversiones fallidas, vacías o infrautilizadas acometidas por las Comunidades Autónomas y los gobiernos locales. Se abordan los déficit de marco institucional y de gobernanza te…
Megacities without Global Functions.
2007
Present urban evolution is characterized by two major phenomena. On the one hand, the number of very large cities, the megacities, increases dramatically, especially in the less developed countries (LDCs). On the other hand, globalization leads to the emergence of cities coordinating complex and global economic activities, the global cities, especially in the more developed countries (MDCs). So, the two phenomena are diverging. A number of megacities do not exhibit any global function.The global performances of megacities are well correlated with their degree of economic development. But it is worth wondering why economic underdevelopment is consistent with urban growth but not with city gl…
Nrg1 haploinsufficiency alters inhibitory cortical circuits
2021
Neuregulin 1 (NRG1) and its receptor ERBB4 are schizophrenia (SZ) risk genes that control the development of both excitatory and inhibitory cortical circuits. Most studies focused on the characterization ErbB4 deficient mice. However, ErbB4 deletion concurrently perturbs the signaling of Nrg1 and Neuregulin 3 (Nrg3), another ligand expressed in the cortex. In addition, NRG1 polymorphisms linked to SZ locate mainly in non-coding regions and they may partially reduce Nrg1 expression. Here, to study the relevance of Nrg1 partial loss-of-function in cortical circuits we characterized a recently developed haploinsufficient mouse model of Nrg1 (Nrg1tm1Lex). These mice display SZ-like behavioral d…
Planktonic foraminifera in ODP Hole 160-963A
2006
New faunal and floral records from Ocean Drilling Project Hole 963A, resolved at ?80-year spacing, provide evidence of suborbital scale climate variability in the central Mediterranean Sea throughout Marine Isotope Stage (MIS) 5. Cold events in the central Mediterranean Sea, indicated by low abundances of warm species and high abundances of cold species, are also evident in a planktonic foraminifera paleoclimatic curve. They have been linked to NGRIP Greenland ice core “C” events and appear correlative with similar sub-millennial climate fluctuations identified in the North Atlantic region and in the Alboran Basin (Westernmost Mediterranean). Low-resolution benthic and planktonic Oxygen Iso…
The Real Effect of Financial Crises in the European Transition Economies
2010
Working Paper GATE 2009-20; International audience; The aim of this work is to assess the impact of financial crises on output for 11 European transition economies (CEECs). The results suggest that financial crises have a significant and permanent effect, lowering long-term output by about 17 percent. The effect is more important in smaller countries, with relative higher dependence on external financing, and in which the banking sector noticed more important financial disequilibria. We also found that fiscal policy measures have been the most efficient tools in dealing with the crises, while the role of monetary policy instruments has been rather blinded. Exchange rate resulted to be more …
Multiplicity of fixed points and growth of ε-neighborhoods of orbits
2012
We study the relationship between the multiplicity of a fixed point of a function g, and the dependence on epsilon of the length of epsilon-neighborhood of any orbit of g, tending to the fixed point. The relationship between these two notions was discovered before (Elezovic, Zubrinic, Zupanovic) in the differentiable case, and related to the box dimension of the orbit. Here, we generalize these results to non-differentiable cases introducing a new notion of critical Minkowski order. We study the space of functions having a development in a Chebyshev scale and use multiplicity with respect to this space of functions. With the new definition, we recover the relationship between multiplicity o…
Next-Day Bitcoin Price Forecast
2019
This study analyzes forecasts of Bitcoin price using the autoregressive integrated moving average (ARIMA) and neural network autoregression (NNAR) models. Employing the static forecast approach, we forecast next-day Bitcoin price both with and without re-estimation of the forecast model for each step. For cross-validation of forecast results, we consider two different training and test samples. In the first training-sample, NNAR performs better than ARIMA, while ARIMA outperforms NNAR in the second training-sample. Additionally, ARIMA with model re-estimation at each step outperforms NNAR in the two test-sample forecast periods. The Diebold Mariano test confirms the superiority of forecast …
