Restructuring the welfare state: reforms in long-term care in Western European countries

Faced with the problems associated with an ageing society, many European countries have adopted innovative policies to achieve a better balance between the need to expand social care and the imperative to curb public spending. Although embedded within peculiar national traditions, these new policies share some characteristics: (a) a tendency to combine monetary transfers to families with the provision of in-kind services; (b) the establishment of a new social care market based on competition; (c) the empowerment of users through their increased purchasing power; and (d) the introduction of funding measures intended to foster care-giving through family networks. This article presents the most significant reforms recently introduced in six European countries (France, Germany, Italy, the Netherlands, Sweden and the UK) as regards long-term care. It analyses their impact at the macro- (institutional and quantitative), meso- (service delivery structures) and micro-level (families, caregivers and people in need). As a result the authors find a general trend towards convergence in social care among the countries, and the emergence of a new type of government regulation designed to restructure rather than to reduce welfare programmes

Preparation of decoherence-free, subradiant states in a cavity

The cause of decoherence in a quantum system can be traced back to the interaction with the environment. As it has been pointed out first by Dicke, in a system of N two-level atoms where each of the atoms is individually dipole coupled to the environment, there are collective, subradiant states, that have no dipole coupling to photon modes, and therefore they are expected to decay slower. This property also implies that these type of states, which form an N-1 dimensional subspace of the atomic subsytem, also decohere slower. We propose a scheme which will create such states. First the two-level atoms are placed in a strongly detuned cavity and one of the atoms, called the control atom is excited. The time evolution of the coupled atom-cavity system leads to an appropriately entangled state of the atoms. By applying subsequent laser pulses at a well defined time instant, it is possible to drive the atomic state into the subradiant, i. e., decoherence free subspace. Up to a certain average number of the photons, the result is independent of the state of the cavity. The analysis of the conditions shows that this scheme is feasible with present day techniques achieved in atom cavity interaction experiments.Comment: 5 page

Complete eigenstates of identical qubits arranged in regular polygons

We calculate the energy eigenvalues and eigenstates corresponding to coherent single and multiple excitations of an array of N identical qubits or two-level atoms (TLA's) arranged on the vertices of a regular polygon. We assume only that the coupling occurs via an exchange interaction which depends on the separation between the qubits. We include the interactions between all pairs of qubits, and our results are valid for arbitrary distances relative to the radiation wavelength. To illustrate the usefulness of these states, we plot the distance dependence of the decay rates of the n=2 (biexciton) eigenstates of an array of 4 qubits, and tabulate the biexciton eigenvalues and eigenstates, and absorption frequencies, line widths, and relative intensities for polygons consisting of N=2,...,9 qubits in the long-wavelength limit.Comment: Added a figure showing how these results can be used to compute deviations from "equal collective decoherence" approximation

Organised decentralization, uneven outcomes : employment relations in the Italian public health sector

This article looks at the difficulties of adapting a very centralised employment relations system in a country characterised by a deep regional economic divide. In particular, by looking at the Italian public health sector, it is contended that organised decentralisation of employment relations implemented against wide regional differences led to uneven outcomes in second-level (organisation) collective bargaining

Collective states in highly symmetric atomic configurations, and single-photon traps

Abbreviated Abstract: We study correlated states in a circular and linear-chain configuration of identical two-level atoms containing the energy of a single quasi-resonant photon in the form of a collective excitation, where the collective behaviour is mediated by exchange of transverse photons between the atoms. For a circular configuration of atoms the effective Hamiltonian on the radiationless subspace of the system can be diagonalized analytically. In this case, the radiationless energy eigenstates carry a $\mathbb{Z}_N$ quantum number $p=0,1, ..., N$ which is analogous to the angular momentum quantum number $l= 0, 1, ...$, carried by particles propagating in a central potential, such as a hydrogen-like system. Just as the hydrogen s-states are the only electronic wave functions which can occupy the central region of the Coulomb potential, the quasi-particle corresponding to a collective excitation of the circular atomic sample can occupy the central atom only for vanishing $\mathbb{Z}_N$ quantum number $p$. For large numbers of atoms in a maximally subradiant state, a critical interatomic distance of $\lambda/2$ emerges both in the linear-chain and the circular configuration of atoms. The spontaneous decay rate of the linear configuration exhibits a jump-like "critical" behaviour for next-neighbour distances close to a half-wavelength. Furthermore, both the linear-chain and the circular configuration exhibit exponential photon trapping once the next-neighbour distance becomes less than a half-wavelength, with the suppression of spontaneous decay being particularly pronounced in the circular system. In this way, circular configurations containing sufficiently many atoms may be natural candidates for {\it single-photon traps}.Comment: Invited contribution to "Xth International Conference on Quantum Optics ICQO 2004" in Minsk, Belarus.

Core repulsion effects in alkali trimers

The present paper is related to a talk presented during the Symposium on Coherent Control and Ultracold Chemistry held during the Sixth Congress of the International Society for Theoretical Chemical Physics (ISTCP-VI, July 2008). The talk was entitled "Electronic structure properties of alkali dimers and trimers. Prospects for alignment of ultracold molecules". Here we report on the electrostatic repulsion forces of the ionic cores at short separation, involved when the potential energy surfaces of alkali trimers are calculated with a quantum chemistry approach based on effective large-core potentials for ionic core description. We demonstrate that such forces in the triatomic molecule can be obtained as the sum of three pairwise terms. We illustrate our results on the lowest electronic states of Cs$_3$, which are computed for the first time within a full configuration interaction based on a large Gaussian basis set. As a preliminary section, we also propose a brief introduction about the importance of alkali trimer systems in the context of cold and ultracold molecules

Trade unions and social policies: The case of Italy

This article presents and exploratory investigation of how trade unions address the issue of representation in the domain of social policies, especially when they have the capacity to influence policy-making, both through political pressure and involvement in social concertation. After presenting two contrasting approaches to trade union representation in the policy domains, one firmly rooted in reflecting the members’ interests and the second more open to consider the proactive interpretation of those interests and other institutional and political factors, the case of trade union confederations in Italy in taken into consideration. A first analysis of the positions of Italian confederation in the area of social policies since the 1960s shows some distinctions between different policy areas: while their attitudes on social transfers maintained a focus on the interests of members, the positions on social services have consistently supported inclusion. Moreover, even in the field of social transfer, a more inclusive approach has progressively emerged in recent decades, including because membership changes through time and organisational revitalisation almost necessarily involves renewal and expansion of the membership base. Although it must be considered a preliminary result, the analysis shows the importance of developing and applying a more dynamic and less deterministic analytical framework to trade union representation in the field of social policie
