Is There an Opportunity to Establish the Social-Capitalism in the Post Socialist Transition?

Recently Claus Offe has put the question that concerns the fate of the European model of social capitalism: Can the model of social capitalism survive the European integration in the context of certain contemporary tendencies? Offe has presupposed that the mentioned model is challenged by the processes of globalization and the integration of the post socialist countries into the European Union. The working hypothesis of the article is that there is an opportunity to provide a coherent answer to this question. The article consists of two parts. In the first part the author starts with the Polanyis socio-economic theory and emphasises the importance of this approach for the analysing of the tendencies of capitalism in Western Europe and in the post socialist countries. The author argues that with the Polanyis theory we are able to explicate the forms of the embedded liberalism in Western Europe after 1945 and the orientation of non-embedded neo-liberalism and the functioning of the workfare state after the crisis of the Keynesian welfare state. Despite the tendencies of the globalisation projected by neo-liberalism, the central element of the social capitalism, namely, the welfare state, remains with the dimensions of the continuity. In the next part the author points out that there is an asymmetrical structure between the Western-Europe and non-Western part of Europe concerning the socialisation of capitalism. The neoliberalisation in accordance with the model of the transfer of ideal-type of capitalism is more strongly implemented in the countries of transition. In addition, the mentioned theoretical approach provides opportunities to explain the failures of implementing of neo-liberalism in the post socialist countries. On the basis of the endorsing of the socio-economic aspects we can adress the issue pointed out by Offe.Karl Polanyi, Transition, Social capitalism, Welfare state

Matchmaking Framework for B2B E-Marketplaces

In the recent years trading on the Internet become more popular. Online businesses gradually replace more and more from the conventional business. Much commercial information is exchanged on the internet, especially using the e-marketplaces. The demand and supply matching process becomes complex and difficult on last twenty years since the e-marketplaces play an important role in business management. Companies can achieve significant cost reduction by using e-marketplaces in their trade activities and by using matchmaking systems on finding the corresponding supply for their demand and vice versa. In the literature were proposed many approaches for matchmaking. In this paper we present a conceptual framework of matchmaking in B2B e-marketplaces environment.B2B Electronic Marketplaces, Conceptual Framework, Matchmaking, Multi- Objective Genetic Algorithm, Pareto Optimal

Microscopic Vortex Velocity in the Inner Crust and Outer Core of Neutron Stars

Treatment of the vortex motion in the superfluids of the inner crust and the outer core of neutron stars is a key ingredient in modeling a number of pulsar phenomena, including glitches and magnetic field evolution. After recalculating the microscopic vortex velocity in the inner crust, we evaluate the velocity for the vortices in the outer core for the first time. The vortex motion between pinning sites is found to be substantially faster in the inner crust than in the outer core, v_0^{\rm crust} \sim 10^{7}\mbox{\cms} \gg v_0^{\rm core} \sim 1\mbox{\cms}. One immediate result is that vortex creep is always in the nonlinear regime in the outer core in contrast to the inner crust, where both nonlinear and linear regimes of vortex creep are possible. Other implications for pulsar glitches and magnetic field evolution are also presented.Comment: Accepted for publication in MNRA

On the enhanced X-ray emission from SGR 1900+14 after the August 27th giant flare

We show that the giant flares of soft gamma ray repeaters (E similar to 10(44) erg) can push the inner regions of a fall-back disk out to larger radii by radiation pressure, while matter remains bound to the system for plausible parameters. The subsequent relaxation of this pushed-back matter can account for the observed enhanced X-ray emission after the August 27(th) giant flare of SGR 1900+14

On Young Neutron Stars as Propellers and Accretors with Conventional Magnetic Fields

The similarity of rotation periods of, the anomalous X-ray pulsars (AXPs), the soft gamma ray repeaters (SGRs) and the dim thermal neutron stars (DTNs) suggests a common mechanism with an asymptotic spindown phase through the propeller and early accretion stages. The DTNs are in the propeller stage. Their luminosities arise from frictional heating in the neutron star. If the 8.4 s rotation period of the DTN RXJ 0720.4-3125 is close to its rotational equilibrium period, the propeller torque indicates a magnetic field in the 10$^{12}$ Gauss range. The mass inflow rate onto the propeller is of the order of the AXP accretion rates. The limited range of rotation periods, taken to be close to equilibrium periods, and magnetic fields in the range 5 E11- 5 E12 Gauss correspond to mass inflow rates 3.2 E14 gm/s < \dot{M} < 4.2 E17 gm/s. Observed spindown rates of the AXPs and SGRs also fit in with these fields rather than magnetar fields periods. The source of the mass inflow is a remnant accretion disk formed as part of the fallback during the supernova explosion. These classes of sources thus represent the alternative pathways for those neutron stars that do not become radio pulsars. For the highest mass inflow rates the propeller action may support enough circumstellar material so that the optical thickness to electron scattering destroys the X-ray beaming, and the rotation period is not observable. These are the radio quiet neutron stars (RQNSs) at the centers of supernova remnants Cas A, Puppis A, RCW 103 and 296.5+10.Comment: 28 pages, with one figure and one table. Submitted to Ap
