Central and east European social policy and European union accession - time for reflections

European Union enlargement and accession are reflexive of both EU and post-communist social policies. There is a unique “dialogue“ going on, indicative of fundamental aspects of post-communist, post-transitional social policy. It is also a 'mirror' that reflects shortcomings of governance, and often presents a neglected institutional landscape. Therefore, the Europeanisation of social policy is an essential transformation process for post-communist countries whereby a new language and new concepts are introduced, the outlines of new social-policy governance emerge and enter the space in which social policy is formulated and considered.European Union Accession, social policy, institutionalism

Corrections to gauge theories in effective quantum gravity with a cutoff

We calculate the lowest order quantum gravity contributions to QED beta function in an effective field theory picture with a momentum cutoff. We use a recently proposed 4 dimensional improved momentum cutoff that preserves gauge and Lorentz symmetries. We find that there is non-vanishing quadratic contribution to the photon 2-point function but that does not lead to the running of the original coupling after renormalization. We argue that gravity cannot turn gauge theories asymptotically free.Comment: 11 pages, 1 figur

Fermion Condensate as Higgs substitute

A dynamical symmetry breaking model of electroweak interactions is investigated based on strongly interacting fermions. Vector-like fermions of different representations of the weak SU(2) form a symmetry breaking condensate and generate the lepton and quark masses. The weak gauge bosons get their usual standard model masses from a gauge invariant effective Lagrangian of a doublet scalar field composed of the new fermion fields. Gap equations are derived and the conditions for finding a symmetry breaking solution are presented. The parameters of the model are constrained further by perturbative unitarity. The oblique electroweak corrections only slightly constrain the model. It is shown that the new charged fermions are produced at the next linear colliders in large number and the cross section for the LHC is presented.Comment: 27 pages, 11 figure

External deficits in the Baltics 1995 to 2007: Catching up or imbalances

This paper studies external deficits in the Baltics between 1995 and 2007.It uses a calibrated small-open-economy dynamic general equilibrium model incorporating a financial accelerator to assess to what extent deficits can be explained by productivity growth, fall in spreads and increasing access to credit.Results suggest that the external deficit and other key macroeconomic aggregates can be well fitted by the equilibrium response of the model economy. Real convergence is found to have been dominant in the first half of the sample. More reversible financial factors became increasingly important towards the end of the period pointing to growing vulnerability. Positive growth outlook is also likely to have played a significant role in the build up of the foreign debt. Reversal scenarios confirm the need for a sizable readjustment.Baltic States financial accelerator dynamic general equilibrium Roeger Lendvai External Deficits in the Baltics 1995 to 2007 Catching Up or Imbalances

OBLIQUE RADIATIVE CORRECTIONS IN THE VECTOR CONDENSATE MODEL OF ELECTROWEAK INTERACTIONS

Oblique radiative corrections are calculated to the parameter $S$ in a version of the standard model where the Higgs doublet is replaced by a doublet of vector bosons and the gauge symmetry is broken dynamically. We show that to each momentum scale there exists a domain of the masses of charged and neutral vector bosons where $S$ is compatible with the experiments. At a scale of 1 TeV this requires vector boson masses of at least $m_0 \approx$ 400--550 GeV, $m_+ \approx$ 200--350 GeV.Comment: 6 pages LATEX, 1 Latex figure include

Resonance Production of Three Neutral Supersymmetric Higgs Bosons at LHC

Multiple production of Higgs particles is essential to study Higgs self-couplings at future high-energy colliders. In this paper we calculated the resonance contributions to the production of three lightest neutral supersymmetric Higgs bosons in gluon fusion at LHC. The cross sections due to trilinear Higgs couplings is sizeable but the measurement of the quartic coupling hhhH(h) seems to be impossible.Comment: 8 pages, 3 figure

ρ\rho Parameter in the Vector Condensate Model of Electroweak Interactions

In the standard model of electroweak interactions the Higgs doublet is replaced by a doublet of vector bosons and the gauge symmetry is broken dynamically. This generates masses for the gauge bosons and fermions, as well as it fixes the interactions in the model. The model has a low momentum scale. In this note we show that the model survives the test of the $\rho$ parameter, and to each momentum scale $\rho$ chooses a possible range of vector boson masses.Comment: 3 pages, 2 figs, Te
