    This is the first study comparing the financial characteristics and pricing processes of asset securitization (AS) and covered bonds (CB) . Using a sample of 6,191 AS bonds and 1 1,471 CB issued by Western European banks between January 1, 2000 and October 31, 2012, we find that AS and CB are not priced in integrated bond markets. Our results show that credit spreads are higher for ABS than for public CB in both pre - and crisis periods. Considering bonds backed by mortgages, w e only find evidence of CB credit spread s being lower than those of AS bonds during the pre - crisis period. Both AS and CB credit spreads are driven by collateral type , credit rating is the most important pricing factor for AS bonds, and we document that not only specific effects related to issuance , but also macro factors and exogenous events are relevant drivers for CB credit spreads. Further more, while the first CB purchase programme led to lower mortgage CB credit spreads, the second programme did not have the ECB ’s desired effects . Finally, we find that the ECB’s second programme reduces ABS spreads significantly for tranches issued by non - German banks.info:eu-repo/semantics/publishedVersio

    A secção UAciência é coordenada pelo Professor Universitário Armindo Rodrigues.A União Europeia considera “rara” uma doença que afete menos do que 5 em cada 10000 pessoas. Estão atualmente descritas cerca de 7000 doenças raras, uma parte substancial das quais e de natureza genética e permanece sem tratamento ou cura. A doença de Machado-Joseph (DMJ) e uma doença globalmente rara que tem merecido especial atenção nos Açores, dada a elevada prevalência que atinge nestas ilhas. Apesar da DMJ permanecer sem intervenção farmacológica especifica, vive-se atualmente um período de grande expetativa, dada a emergência recente de resultados relativos aos primeiros ensaios clínicos. A investigação de nível clínico e alicerçada num trabalho “pré-clínico” no qual se usam, habitualmente, modelos animais (tais como o ratinho, vulgarmente designado de murganho), para avaliar e selecionar compostos com potencial suficiente para serem testados em doentes, num ensaio clínico.

    A investigação desenvolvida no âmbito do projeto Estratégias de Intervenção socioeducativa em contextos sociais complexos enquadra-se na avaliação das políticas sociais e educativas, em particular no que diz respeito à segurança escolar em contextos marcados pela diversidade e complexidade social e cultural. O processo de avaliação centrou-se na análise das estratégias de intervenção socioeducativa relativas ao problema da violência na escola, desenvolvidas em três escolas de um concelho da Área Metropolitana de Lisboa. Partindo do pressuposto que a violência na escola é um fenómeno multideterminado e multifacetado, a pesquisa centrou-se numa abordagem que enquadra as esferas de intervenção/ação das instituições formais e dos agentes sociais enquanto mecanismos que estruturam e regulam as concepções e práticas de violência na escola. A recolha e sistematização de informação centrou-se, por um lado, nas estratégias de intervenção que têm vindo a ser desenvolvidas localmente pelas escolas, e, por outro, nas perspetivas dos diferentes intervenientes, considerando-se os alunos, osprofessores, as direções escolares e representantes das entidades e instituições locais. Metodologicamente, privilegiou-se o cruzamento de métodos de carácter extensivo e intensivo, combinando técnicas como a Observação Direta, a realização de Entrevistas, de Grupos Focais, de Questionários, e ainda, a Análise de Redes e a Análise Documental. Numa fase posterior, os diversos intervenientes participaram na discussão e análise dos resultados previamente recolhidos, e na validação conjunta de uma metodologia de intervenção que define um conjunto de estratégias gerais de combate às situações de violência na escola e nos territórios educativos. Esta metodologia é o principal produto do projeto e resulta de um processo de avaliação dinâmico e participado. A contribuição que se apresenta no VI Encontro do CIED ocupa-se dos procedimentos de avaliação desenvolvidos no âmbito deste projeto.Abstract: The research developed through the project Estratégias de Intervenção socioeducativa em contextos sociais complexos concerns the assessment of social and educational policies, particularly in what regards safety in school contexts marked by social and cultural complexity and diversity. The assessment focused on the analysis of the social and educational intervention strategies of three schools of the Lisbon Metropolitan Area on the problem of school violence. Assuming that school violence is a multidetermined and multifaceted phenomenon the research engaged an approach that includes the intervention/action of formal institutions and of social agents as mechanisms that structure and regulate conceptions and practices of school violence. The gathering and systematization of information was centered on the intervention strategies developed locally by the schools, on one hand, and the perspectives of the different stakeholders, on the other hand, considering students, teachers, school directors and representatives from the local organizations and institutions. The methodology intersected extensive and intensive methods, combining techniques such as Observation, Interviews, Focus Groups, Questionnaires, Social Network Analysis and Document Analysis. At the final stage, the various actors were involved on the discussion and analysis of the results, as well as the validation of an intervention strategy to deal with school violence. This strategy was the main result of the projectand resulted from a dynamic assessment and participative procedures. The presentation at the VI CIED Conference focused on the procedures and key outputs of this research project

    Urinary tract infections on the Portuguese general practitioner sentinel network - preliminary data 2016

    Get PDF
    Urinary tract infections (UTIs) are inflammatory processes of infectious cause, which can reach the upper and/or lower urinary tract. UTIs, after respiratory infections, are the most frequent in the community, with a higher incidence in females. They can be classified according to anatomical location: in cystitis (low UTI) where the presence of bacteria is limited to the bladder; and pyelonephritis (high UTI) defined as that affecting the pelvis and renal parenchyma. Escherichia coli is responsible for 75 to 90% of the cases. The high rates of resistance of E. coli to quinolones and co-trimoxazol described in Portugal are likely to be a consequence of the prescription abuse of these antibiotics over the last few decades and may increase the risk of antibiotic failure. When the antibiotic prescribing decision is based on the knowledge of the main microbial agents involved and its sensitivity profile is known, allowing guidelines to be adjusted to the current reality, empirical antibiotic therapy is associated with eradication rates equal to or greater than 90%.N/

    Educational policies, territories and actors strategies

    The purpose of this paper is to analyse how educational policies about school violence are reinterpreted and implemented at school level and if this process contributes to a more pluralistic and democratic school. A research carried out in 3 clusters of schools showed that the diversity of understandings and strategies to face school violence, higher within the territories than between them, was associated to the school board's agendas and the legitimacy of the different actors to interpret and act within the national policies framework. There was a high consistency between violence management strategies and the ways schools faced social and cultural diversity. Those who favour more inclusive strategies to deal with violence tend to provide higher educational opportunities in schools, inversely, those who favour repressive strategies are more likely to support educational and social selective strategies, with less educational offer; less participation of teachers, students and parents in violence regulation

    The ROCK Lisbon Survey was designed and implemented by the ICS research team under the coordination of Roberto Falanga (co-Principal Investigator at the host institution). The survey was structured into seven sections: Cultural Heritage, Urban Changes, Urban Voids, Urban Mobility, Local Economy, Future, Citizen Participation, and ROCK Project. Data collection was undertaken between May and August 2019 in the ROCK intervention area including the following neighbourhoods in the parishes of Beato and Marvila (Lisbon): Bairro do Marquês de Abrantes; Bairro dos Alfinetes; Ex-Cooperativas (Avenida Paulo VI); Bairro da Quinta do Chalé; Bairro da PRODAC-SUL; Rua de Marvila; Vilas e Pátios no Beco dos Toucinheiros; Poço do Bispo e Rua do Açúcar; Xabregas e Rua do Beato. The Stratified Proportional Quota sample in the ROCK intervention area selected 368 people who were identified from available data on resident population, sex and age (Instituto Nacional de Estatistica 2011). The sample reproduced the proportion that the identified groups have in the general population. This report was produced by Rita Correia, who conducted data analysis through descriptive and inferential statistical methods. Qui Square tests and F tests were conducted to provide respectively differences in proportions and means. Corresponding values are presented whenever needed.info:eu-repo/semantics/publishedVersio
