The Trade Offs approach is an advanced tool for the improvement of the discrimination of Data Envelopment Analysis (DEA) models, Meta Malmquist Index was defined by Maria Portella and et. al (2008). In this paper we compute the Meta Malmquist Index in Trade Offs model in DEA and we compare, obtaining results, of Meta Malmquist Index in different models of DEA, Variable Return to Scale (VRS), Co...

In recent years, investigating synchronization of business cycles among countries, after increasing integration of global economies, has been attracted more attention of policy makers and researchers. Perhaps an unknown origin of such similarities, as an open question, is the main reason of these interests. So, with regard to the mentioned question, the aim of this paper is to investigate some ...

For a particle travelling through an interferometer, the trade-off between the available which-way information and the interference visibility provides a lucid manifestation of the quantum mechanical wave-particle duality. Here we analyse this relation for a particle possessing an internal degree of freedom such as spin. We quantify the trade-off with a general inequality that paints an unexpec...

Globalization is integration of national economies in global economy and infers on increasing the flow of goods and services. In this study the consequences of globalization were studied through the analysis of Level of International Trade index (LIT) in the caviar export equation. The required data were gathered from Statistical Yearbook of Foreign Trade, Statistical Yearbook of fisheries, Sta...

Despite its importance for the global hospitality and tourism industry, firm creation remains an under-researched activity, particularly in terms of differences across developing and developed economies. By examining the impact of institutional structure on firm creation across economies of varying development levels, this study aims to address gaps in the literature and inform theory, practice...

We discuss problems and trade-offs with systems providing anonymity for web browsing (or more generally any communication system that requires low latency interaction). We focus on two main systems: the Freedom network [12] and PipeNet [8]. Although Freedom is efficient and reasonably secure against denial of service attacks, it is vulnerable to some generic traffic analysis attacks, which we d...

Humans exposed to war and terrorist attacks are at risk for the development of posttraumatic stress disorder (PTSD). Numerous reports indicate that the incidence of PTSD in both returning Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) military personnel and survivors of the 9/11 World Trade Center (WTC) attacks is significant. These situations have served to motivate research on h...

Topological Strings I am going to tell you about some work I have been doing with Kirill Saraikin and Cumrun Vafa, the first part of which has appeared in [1] and the second part will appear soon [2]. Since this is the first talk in this workshop about topological strings, I would like to start by introducing topological strings and describing some of their properties. For our purposes we will ...
