Political training and social change in the 1960s and 1970s: The educational activities of the Latin American central of workers (CLAT)

This article reconstructs the educational policies of the Latin American Confederation of Christian Trade Unions (CLASC)—the name of which was later changed to the Latin American Central of Workers (CLAT) —in the context of the Latin American Cold War. It provides an empirical description of its pedagogical praxis, showing how it was shaped in constant dialogue with the region's conflictive context. It explores how they viewed political training in relation to both their organizing efforts and struggles, applying a conception that brought together “action, organization and training” as integrated elements, in the run to foster class awareness, build up a “new society,” and “workers’ organized power”.Fil: Scodeller, Gabriela Noemi.

The rise of goods-market competition and the fall of nominal wage contracting: endogenous wage contracting in a multisector economy

This paper shows how heterogeneity wage-setting and a link between nominal wage flexibility andg goods-market competition rise in a multisector economy that is affected by aggregate and sector-specific shocks. Aggregate volatility increases the variance of real contract wages, whereas sectoral volatility increase the relative variance of real Walrasian wages. Given this tradeoff, the prevalence of nominal wage contracting reflects both the relative volatility of aggregate versus sectoral disturbances and the overall degree of goods-market market competition. We find that these variables help explain the decline in unionization (a proxy for contracting in) the United States.Markets ; Wages

Copyright versus Patents: the Open Source Software Legal Battle

Open Source Software is often viewed as an anti-intellectual property regime. By contrast, we argue how IP law is at the heart of open source model since licenses that organize the innovation and business relationships between developers, distributors and end-users are based on copyright law. The proliferation of software patents can, however be seen as a threat for the development and deployment of open source software. We present the nature of the threat and review a series of initiatives undertaken by the open source community to address them effectively. These initiatives, such as the redesign of licenses and the creation of patent commons, are a testiment to a genuinely creative use of IP law by the open source community, not its undermining.Open Source Software; Patent; Hold-Up; Copyright; Copyleft; Intellectual Property

Spectral Investigations of the nature of the Sco X-1 like sources

We present results of spectral investigations of the Sco X-1 like Z-track sources Sco X-1, GX 349+2 and GX 17+2 based on Rossi-XTE observations using an extended accretion disk corona model. The results are compared with previous results for the Cyg X-2 like group: Cyg X-2, GX 340+0 and GX 5-1 and a general model for the Z-track sources proposed. On the normal branch, the Sco-like and Cyg-like sources are similar, the results indicating an increase of mass accretion rate Mdot between soft and hard apex, not as in the standard view that this increases around the Z. In the Cyg-like sources, increasing Mdot causes the neutron star temperature kT to increase from ~1 to ~2 keV. At the lower kT, the radiation pressure is small, but at the higher kT, the emitted flux of the neutron star is several times super-Eddington and the high radiation pressure disrupts the inner disk launching the relativistic jets observed on the upper normal and horizontal branches. In the Sco-like sources, the main physical difference is the high kT of more than 2 keV on all parts of the Z-track suggesting that jets are always possible, even on the flaring branch. The flaring branch in the Cyg-like sources is associated with release of energy on the neutron star consistent with unstable nuclear burning. The Sco-like sources are very different as flaring appears to be a combination of unstable burning and an increase of Mdot which makes flaring much stronger. Analysis of 15 years or RXTE ASM data on all 6 classic Z-track sources shows the high rate and strength of flaring in the Sco-like sources suggesting that continual release of energy heats the neutron star causing the high kT. A Sco X-1 observation with unusually little flaring supports this. GX 17+2 appears to be transitional between the Cyg and Sco-like types. Our results do not support the suggestion that Cyg or Sco-like nature is determined by luminosity.Comment: Astronomy and Astrophysics in press; 21 pages, 13 figure

NON-TRADABLE GOODS IN CATCHING-UP EUROPEAN COUNTRIES – AN INSTITUTIONAL PUZZLE?

This text aims to shed more light on the problem of delays and divergence tendencies in the process of real convergence compared to price level convergence in the case of publicly funded and governed goods and services (merit goods) in selected new EU member states. Since this topic is only briefly overviewed in Égert (2007), whose study focuses mainly on market goods and services, this text examines changes in real volumes and price levels for non-market goods and services. Given data limitation and regional heterogeneity, the focus is on the period between 1999 and 2012 and four selected CEE countries (the Visegrad group). Our preliminary results reveal that there were at least two (three) main tendencies similar across the group of countries during the aforementioned period: a rapid catching up process in the pre-EU period (both real and nominal convergence), some sort of an ‘EU effect’, followed by differentiation resulting from heterogeneous impacts of the on-going sovereign debt (financial) crisis on the chosen group of CEE countries
