Search for new particles at CDFII

We report on the first results from the CDF experiment on search for physics beyond the Standard Model using data from the upgraded TeVatron collider running $p\bar p$ collisions at $\sqrt{s}$ = 1960 GeV. These first results, although obtained with a total integrated luminosity lower than the total integrated luminosity collected during Run I, are already competitive if not better, due to the increase in the center of mass energy and the improved detector capability.Comment: writeup of the talk given at XXXVIIIth Rencontres de Moriond on Electroweak Interactions and Unified Theories, Les Arcs March 200

Fragmentation Functions approach in pQCD fragmentation phenomena

Next-to-leading order parton fragmentation functions into light mesons are presented. They have been extracted from real and simulated $e^+e^-$ data and used to predict inclusive single particle distributions at different machines.Comment: proceeding of the XXXI Rencontres de Morion

New policy challenges from financial integration and deepening in the emerging areas of Asia and Central and Eastern Europe

Since the mid-nineties international financial integration has advanced gradually in the emerging areas of Asia, while it has progressed rapidly in Central and Eastern Europe. This process has helped provide long-term benefits for the economies of the two regions in terms of faster productivity growth and deepening of domestic financial markets. The strong surge of international capital inflows since the early years of the current decade has, however, also potentially increased the financial vulnerability and the external sources of contagion for a number of countries, particularly those in Central and Eastern Europe that have seen a significant increase in their foreign borrowing, and also those with still relatively underdeveloped financial systems. We thus analyze the risks of financial instability and asset bubbles in the emerging economies of the two regions, taking into account the degree of development of their domestic financial systems. We conclude by discussing possible policy responses to these challenges by the monetary authorities of the concerned countries.Asian economies, Central and Eastern European economies, capital markets, international financial integration

Relative second bounded cohomology of free groups

This paper is devoted to the computation of the space $H_b^2(\Gamma,H;\mathbb{R})$, where $\Gamma$ is a free group of finite rank $n\geq 2$ and $H$ is a subgroup of finite rank. More precisely we prove that $H$ has infinite index in $\Gamma$ if and only if $H_b^2(\Gamma,H;\mathbb{R})$ is not trivial, and furthermore, if and only if there is an isometric embedding $\oplus_\infty^n\mathcal{D}(\mathbb{Z})\hookrightarrow H_b^2(\Gamma,H;\mathbb{R})$, where $\mathcal{D}(\mathbb{Z})$ is the space of bounded alternating functions on $\mathbb{Z}$ equipped with the defect norm.Comment: 14 pages. small corrections; this version has been accepted for publication by Geometriae Dedicat

Comparative Advantage Patterns and Domestic Determinants in Emerging Countries: An Analysis with a Focus on Technology

During the last two decades a number of emerging economies have become deeply engaged in technology-intensive production. This has been reflected in their international trade specialization shifting from labour-intensive goods towards capital-intensive ones, and in rapid productivity gains across all manufacturing activities. The paper investigates for a sample of sixteen emerging countries, the linkages between the pattern of revealed comparative advantages (RCAs), captured by a modified version of the Lafay index of international trade specialization, and the competitiveness structure of the domestic manufacturing sector, measured by a set of industry and country-specific variables. Positive and large RCAs are found to be associated with low unit labour costs in both low-technology (high labour-intensive) and medium- or high tech sectors. On the other hand, domestic accumulation of physical capital is associated with positive and large RCAs in medium- or high technology sectors. The international disadvantage (negative RCAs) in technology-intensive production tends to deepen for countries with low human capital, whereas it diminishes for countries with large domestic markets importing technology through foreign capital goods.revealed comparative advantages, technological up-grading

Improvement of the Compilation Process of the Italian Income Certifications: A Methodology Based on the Evaluation of the Information Content (Part 1)☆

Abstract In recent years the Italian tax system has been affected by significant changes. Important legislative reforms have revolutionized the relationship between citizens and public administration. These changes tried to simplify the relationship between citizens and public administration, reducing the burden of bureaucracy on the lives of citizens and businesses. To simplify the completion of income statement taxpayers, the Italian Revenue Agency started to use precompiled statement from 2015. However, many manual actions are still necessary to correct or complete the statement. This paper focuses on the improvement of compilation and control of income certifications in order to reduce non-compliance poured into precompiled statements. The proposed method aims to improve the process by introducing a robust procedure based on Axiomatic Design that is able to quantify the information content of a software project by measuring the information content through the Function Point technique. The developed approach will be able to prevent the generation of non-compliances. In this way, to identify possible critical situations in a proactive way and to avoid classes of non-conformities, it will be possible to optimize the data compilation process to verify compliance with the technical specifications of the Italian Revenue Agency. The goal of the proposed approach is to simplify the collection of fiscal data and create a clearer path for taxpayers
