Australia has a network of Federally funded disability employment and vocational rehabilitation services, including a proportion of outlets that specialise in providing services for persons with psychiatric disabilities. However, neither Federal nor State Governments currently provide or fund disability-specific education assistance to persons with psychiatric disabilities. To begin considering whether Specialised Supported Education is indicated for persons with psychotic disorders, we examined data collected in a national 'Survey of Disability, Ageing and Carers Australia, 1998'. International studies of the effectiveness of overseas Supported Education programs were also examined to identify the forms of assistance most likely to warrant consideration in Australia. U.S.A. evidence indicates that Specialised Supported Education is emerging as an effective career development option for persons with psychotic disorders. An example of an innovative Specialised Supported Education program is provided to illustrate how this type of program can be implemented in Australia.

The physical implementation of quantum information processing is one of the major challenges of current research. In the last few years, several theoretical proposals and experimental demonstrations on a small number of qubits have been carried out, but a quantum computing architecture that is straightforwardly scalable, universal, and realizable with state-of-the-art technology is still lacking. In particular, a major ultimate objective is the construction of quantum simulators, yielding massively increased computational power in simulating quantum systems. Here we investigate promising routes towards the actual realization of a quantum computer, based on spin systems. The first one employs molecular nanomagnets with a doublet ground state to encode each qubit and exploits the wide chemical tunability of these systems to obtain the proper topology of inter-qubit interactions. Indeed, recent advances in coordination chemistry allow us to arrange these qubits in chains, with tailored interactions mediated by magnetic linkers. These act as switches of the effective qubit-qubit coupling, thus enabling the implementation of one- and two-qubit gates. Molecular qubits can be controlled either by uniform magnetic pulses, either by local electric fields. We introduce here two different schemes for quantum information processing with either global or local control of the inter-qubit interaction and demonstrate the high performance of these platforms by simulating the system time evolution with state-of-the-art parameters. The second architecture we propose is based on a hybrid spin-photon qubit encoding, which exploits the best characteristic of photons, whose mobility is exploited to efficiently establish long-range entanglement, and spin systems, which ensure long coherence times. The setup consists of spin ensembles coherently coupled to single photons within superconducting coplanar waveguide resonators. The tunability of the resonators frequency is exploited as the only manipulation tool to implement a universal set of quantum gates, by bringing the photons into/out of resonance with the spin transition. The time evolution of the system subject to the pulse sequence used to implement complex quantum algorithms has been simulated by numerically integrating the master equation for the system density matrix, thus including the harmful effects of decoherence. Finally a scheme to overcome the leakage of information due to inhomogeneous broadening of the spin ensemble is pointed out. Both the proposed setups are based on state-of-the-art technological achievements. By extensive numerical experiments we show that their performance is remarkably good, even for the implementation of long sequences of gates used to simulate interesting physical models. Therefore, the here examined systems are really promising buildingblocks of future scalable architectures and can be used for proof-of-principle experiments of quantum information processing and quantum simulation.

Este estudo teve por objetivo investigar quais as representações sociais que os tutores têm, sobre a própria atuação na educação a distância, em cursos de Licenciatura. Com o propósito de analisar se o tutor se reconhece como docente e participante no processo de formação do aluno o estudo de campo teve como sujeitos tutores com formação acadêmica em licenciaturas e que atuam em cursos do mesmo nível nessa modalidade, em instituição particular de Ensino Superior da Grande São Paulo. Os caminhos percorridos para tal investigação justificam-se na trajetória formativa pessoal e nos espaços da experiência que se constroem no cotidiano dessa atividade. Um estudo sobre os modelos disponíveis na modalidade a distância no ensino superior do país, um breve histórico sobre os aspectos da EAD no Brasil e uma explanação sobre o modelo no qual esses tutores atuam, além de uma aproximação com as representações sociais da profissão docente, são abordagens presentes neste trabalho, que pretendeu contribuir para a educação aprofundando conhecimentos sobre o tutor responsável pelo acompanhamento dos alunos nos ambientes virtuais de aprendizagem, considerando as possibilidades de ampliação, de alcance e democratização da educação no país. Os Resultados demonstram que há uma tendência de ser considerada, pelo tutor, uma atuação que se confunde com a essência da profissionalidade docente, numa indicação de que é necessária uma reflexão mais aprofundada sobre a função e a atuação desses profissionais.(AU)
