Game complete analysis for financial markets stabilization

The aim of this paper is to propose a methodology to stabilize the financial markets using Game Theory and in particular the Complete Study of a Differentiable Game, introduced in the literature by David Carfì. Specifically, we will focus on two economic operators: a real economic subject and a financial institute (a bank, for example) with a big economic availability. For this purpose we will discuss about an interaction between the two above economic subjects: the Enterprise, our first player, and the Financial Institute, our second player. The only solution which allows both players to win something, and therefore the only one desirable, is represented by an agreement between the two subjects: the Enterprise artificially causes an inconsistency between spot and future markets, and the Financial Institute, who was unable to make arbitrages alone, because of the introduction by the normative authority of a tax on economic transactions (that we propose to stabilize the financial market, in order to protect it from speculations), takes the opportunity to win the maximum possible collective (social) sum, which later will be divided with the Enterprise by contract.Financial Markets; Game Theory; Stabilization of Financial Markets; arbitrages

First principles study of adsorbed Cu_n (n=1-4) microclusters on MgO(100): structural and electronic properties

We present a density functional study of the structural and electronic properties of small Cu_n (n=1,4) aggregates on defect-free MgO(100). The calculations employ a slab geometry with periodic boundary conditions, supercells with up to 76 atoms, and include full relaxation of the surface layer and of all adsorbed atoms. The preferred adsorption site for a single Cu adatom is on top of an oxygen atom. The adsorption energy and Cu-O distance are E_S-A = 0.99 eV and d_S-A = 2.04 Angstroems using the Perdew-Wang gradient corrected exchange correlation functional. The saddle point for surface diffusion is at the "hollow" site, with a diffusion barrier of around 0.45 eV. For the adsorbed copper dimer, two geometries, one parallel and one perpendicular to the surface, are very close in energy. For the adsorbed Cu_3, a linear configuration is preferred to the triangular geometry. As for the tetramer, the most stable adsorbed geometry for Cu_4 is a rhombus. The adsorption energy per Cu atom decreases with increasing the size of the cluster, while the Cu-Cu cohesive energy increases, rapidly becoming more important than the adsorption energy.Comment: Major revision, Latex(2e) document, 23 pages, 11 figures, accepted for publication in J. of Chem.

Modelling long-term impacts of the transport supply system on land use and travel demand in urban areas

It is commonly accepted that there is a two-way relationship between land use and transport in urban areas. Land use affects transport, conditioning travel demand. Conversely, transport affects land use, conditioning spatial distribution of activities and land market. The problem of simulating mutual interactions between land use and transport has been tackled by socalled Land Use Transport Interaction (LUTI) models. Different modelling approaches are present in literature, which are generally grouped into three main categories: spatial micro-economic, spatial interaction and spatial accounting models. The paper presents a spatial accounting LUTI model, which relies on Multi-Regional-Input-Output (MRIO) framework. The model has two main interacting components: an activity model and a transport model, which allow to endogenously estimate activities generation and location, land prices, travel demand and transport accessibility. The proposed LUTI model has been specified and applied in an urban area, more particularly to the town of Reggio Calabria (Italy). The objective of the application is the estimation of long-term impacts on land use and passenger travel demand patterns when interventions on transport facilities and services are planned at a strategic scale. The results confirm that MRIO framework offers the potentialities to bring activity location, land use in line within travel demand modelling

El Territorio como determinante de la salud comunitaria

Esta propuesta de trabajo está vinculada a reflexionar en torno de las territorialidades y los procesos de organización de las poblaciones y comunidades con el anclaje de las herramientas de la salud colectiva, como procesos de fortalecimiento de dichas organizaciones a través de las disputas por los bienes comunes que impactan sobre la salud. El espacio compartido, disputado y creado colectivamente adquiere sentido para una comunidad. Es comprendido como determinante de los procesos de salud-enfermedad de las subjetividades y de las comunidades; cuyo marco articula multiplicidades de acciones que se desarrollan en el contexto de la vida cotidiana. El capitalismo actual, desgarra al decir de Zibechi (2003) el espacio geográfico; provoca fragmentación y segregación de espacios, cuerpos y subjetividades; cuya respuesta y pretensión estatal es la represión en función de la expropiación y explotación. No sólo de dichos espacios y bienes comunes como mercancías, sino también de los mismos sujetos expulsados. Pensar los procesos de resistencia y ocupación de territorios de las colectividades y poblaciones en clave de salud comunitaria es un aporte en función de habitar y transformar dichos espacios en lugares y contextos en donde se disputa la vida.Fil: Muñoz Rodríguez, Mariela .

The North-South Divide in Italy: Reality or Perception?

lthough the literature about the objective socio-economic characteristics of the Italian North-South divide is wide and exhaustive, the question of how it is perceived is much less investigated and studied. Moreover, the consistency between the reality and the perception of the North-South divide is completely unexplored. The paper presents and discusses some relevant analyses on this issue, using the findings of a research study on the stated locational preferences of entrepreneurs in Italy. Its ultimate aim, therefore, is to suggest a new approach to the analysis of the macro-regional development gaps.What emerges from these analyses is that the perception of the North-South divide is not consistent with its objective economic characteristics. One of these inconsistencies concerns the width of the ‘perception gap’, which is bigger than the ‘reality gap’. Another inconsistency concerns how entrepreneurs perceive in their mental maps regions and provinces in Northern and Southern Italy. The impression is that Italian entrepreneurs have a stereotyped, much too negative, image of Southern Italy, almost a ‘wall in the head’, as also can be observed in the German case (with respect to the East-West divide)

Updated Measurement of the b baryon lifetime

sing about 4 million hadronic Z decays recorded with the Aleph detector, the lifetime of the b baryons has been measured using two independent data samples. From a maximum likelihood fit to the impact parameter distribution of leptons in 1085 Lambda-lepton combinations containing a b baryon sample of 719 decays the measured b baryon lifetime is \tau = 1.18 \pm 0.08(stat) \pm 0.07 (syst) ps The lifetime of the Lambda_b baryon from a maximum likelihood fit to the proper time distribution of 193 Lambda_c-lepton candidates is \tau_{\Lambda_b} = 1.21^{+0.13}_{-0.12}{stat}) \pm 0.04 {syst} ps. The combined result of the two measurements yields an averaged value \tau_{\Lambda_b} = 1.19 \pm{0.0
