In 2008 two laws that changed the didactic- pedagogic and administrative organization of vocational schools were enacted: the Law 11.741/2008, which incorporated the Technical Professional Education for the Middle Level to Basic Education; and Law 11.892/2008,which has transformed Agrotechnical Schools, the CEFET 's and some technical schools linked to universities into Colleges of Education, Science and Technology (IFs). These institutions have been operating at all levels and types of education provided in the Law of Directives and Bases of National Education number 9394/1996, with the exception of Early Childhood Education. Vocational and training schools, which gave origin to the IFs,have historically restricted youth education to teaching professional techniques, but due to the reformist laws, they were led to revise their conceptions of work and education. Thus, the goal of this article is to analyze the concepts of Basic Education and work that permeate these laws and the organization of educational work at IFCE. Have these laws been promoting a rupture with the history of vocational education in the country? Have the IFs been accomplishing a teaching job in addition to technical training? The choice for these questions was motivated by two main reasons: a) Vocational Education in the aforementioned institutions have traditionally been restricted to the qualication of the labor force for learning a technical profession, without relating it to issues that concern basic education; b) The Reform of Basic Education, from 1990 to 2013, was conducted in the context of capital's structural crisis and aimed to adapt the educational system to the demands of productive sectors. Thus, the main objective of this paper is to explain the contradictions that exist in project of formation of the working class, in the context of a conictual society divided into classes, a situation that alienates the youth to live this time forever.

An introduction to bacterial polysaccharides and the methods for structural determination are described in the first two parts of the thesis. In a structural elucidation of bacterial polysaccharides NMR experiments are important as is component analysis. A short description of immunochemical methods such as enzyme immunoassays is included. Two NMR techniques used for interaction studies, trNOE and STD NMR, are also discussed. The third part of the thesis discusses and summarizes the results from the included papers. The structures of the exopolysaccharides produced by two lactic acid bacteria are determined by one- and two dimensional NMR experiments. One is a heteropolysaccharide produced by Streptococcus thermophilus and the other a homopolysaccharide produced by Propionibacterium freudenreichii. The structure of an acidic polysaccharide from a marine bacterium with two serine residues in the repeating unit is also investigated. The structural and immunological relationship between two O-antigenic polysaccharides from Escherichia coli strain 180/C3 and O5 is discussed and investigated. Finally, interaction studies of an octasaccharide derived from the Salmonella enteritidis O-antigen and a bacteriophage are described which were performed with NMR experiments.

Il mar Mediterraneo è un bacino acquifero peculiare per la recente colonizzazione di specie aliene, per l’evento geologico legato alla Crisi di salinità del Messiniano e per l’ampio range di salinità. L’individuazione dei meccanismi di colonizzazione si è incentrata sullo studio morfologico, istologico e molecolare delle specie Asperarca nodulosa ed Anadara demiri (Arcidae-Bivalvia-Mollusca). La ricerca si è basata sulla caratterizzazione morfologica, con utilizzo del microscopio elettronico a scansione, al fine di individuare il tipo di sviluppo larvale. Successivamente i dati rilevati al S.E.M. sono stati supportati dall’indagine istologica che ha evidenziato la presenza di gonadi a sessi distinti e la non incubazione larvale. L’ulteriore analisi filogenetica ha permesso di evidenziare la netta suddivisione tra le tre popolazioni studiate, indagine effettuata tramite marcatori arbitrari (RAPDs) e nucleari specifici (ITS). I risultati ottenuti trovano supporto da quanto noto su base morfologica. I dati, nel complesso, mostrano una perdita delle capacità di diffusione della specie tramite sviluppo larvale plantotrofico a favore di quello lecitotrofico o diretto; tale tesi è ulteriormente supportata dai dati molecolari che mostrano una netta separazione delle popolazioni prese in esame ed un conseguente isolamento tra individui appartenenti a zone di profondità del Mediterraneo (sub-bacini abissali). La ricerca ha, inoltre,esaminato i meccanismi di introduzione attuali nel bacino acquifero che è soggetto ad una nuova invasione da parte specie aliene dovuta all’apertura del canale di Suez. L’analisi si è focalizzata sullo studio per l’ individuazione dell’origine della specie aliena A. demiri , di presunta derivazione Indo-Pacifica, ma rivelatasi, nei dati preliminari, di origine Atlantica.

CONTEXT: Death from corpora aliena in the larynx is a well-known entity in forensic pathology. The correct diagnosis of this cause of death is difficult without an autopsy, and misdiagnoses by external examination alone are common. OBJECTIVE: To determine the postmortem usefulness of modern imaging techniques in the diagnosis of foreign bodies in the larynx, multislice computed tomography, magnetic resonance imaging, and postmortem full-body computed tomography-angiography were performed. DESIGN: Three decedents with a suspected foreign body in the larynx underwent the 3 different imaging techniques before medicolegal autopsy. RESULTS: Multislice computed tomography has a high diagnostic value in the noninvasive localization of a foreign body and abnormalities in the larynx. The differentiation between neoplasm or soft foreign bodies (eg, food) is possible, but difficult, by unenhanced multislice computed tomography. By magnetic resonance imaging, the discrimination of the soft tissue structures and soft foreign bodies is much easier. In addition to the postmortem multislice computed tomography, the combination with postmortem angiography will increase the diagnostic value. CONCLUSIONS: Postmortem, cross-sectional imaging methods are highly valuable procedures for the noninvasive detection of corpora aliena in the larynx.

This work aims to reflect on the concept of social innovation, questioning its explanatory capacity for the discipline of social work. For this purpose, certain on-going debates with regard to this concept are examined and certain minimum dimensions are offered to enable an analysis of the social innovation strategies that certain affected groups implement to meet social needs. The approach is to construct «glasses» that permit an analytical engagement with new realities and with the strategies used by certain social groups to resolve situations of severe vulnerability. Finally, a case study is presented: a strategic group known as the Corrala Utopía that seeks to respond to severe housing problems and is developing in the city of Seville. The article highlights the elements of community social innovation emerging from the experience studied.

A falta de motivação dos profissionais da estratégia de saúde da família dificulta a estruturação e fortalecimento do SUS, sendo necessário construir estratégias de envolvimento e mobilização desses trabalhadores para que efetivamente ocorra a mudança do modelo tecnoasssitencial que a estratégia se propõe a fazer. O objetivo deste trabalho é realizar uma revisão de literatura sobre o processo de trabalho em saúde, analisando a alienação e redução da autonomia dos profissionais e os impactos que estes fatores provocam no desenvolvimento das práticas na estratégia de saúde da família. Partindo dessa compreensão sobre as relações de trabalho na sociedade capitalista e na instituição saúde buscou-se elaborar um plano de ação para valorizar e envolver os trabalhadores na reflexão sobre seu cotidiano e na construção de novas práticas. A metodologia utilizada para esse trabalho foi a seleção de artigos de interesse nas bases eletrônicas de dados bibliográficos e em livros e manuais do Ministério da Saúde. A partir da realização dessa revisão foi observado que o trabalho em saúde, assim como nas outras profissões, aliena e controla o trabalhador, o que provoca o desenvolvimento de práticas repetitivas, pouco reflexivas e normatizadas pelas instituições hegemônicas na sociedade. Esses fatores desmotivam o trabalhador e fragilizam o projeto de transformação do modelo de cuidado do SUS. Conclui-se que é necessário desenvolver estratégias que permitam a mudança desta relação de trabalho, permitindo que os trabalhadores formulem e desenvolvam práticas reflexivas e críticas, com autonomia e liberdade, envolvendo e motivando estes trabalhadores na efetivação do SUS.
