Klappentext: O livro surge como um grande painel em que nos é apresentada a realidade guineense, a propósito da questão da segurança social (...) Naturalmente que o livro não se cinge àquilo que normalmente é considerado o âmbito da segurança social, trazendo-nos uma rica investigação sobre as formas de solidariedade social e religiosa características em geral do Continente Africano (...) O autor manifesta a sua simpatia para com estas formas de organização, que contrastam vivamente com o egoísmo e individualismo das sociedades mais desenvolvidas, mas nem por isso deixa de sublinhar a sua insuficiência, frisando a necessidade de intervenção do Estado e das Organizações Internacionais para uma cobertura correcta dos problemas da segurança social e da saúde (...) O livro de Eugénio Moreira é um importante serviço prestado ao Estado guineense, pela forma reflectida e corajosa como são apresentadas as suas conclusões, ao mesmo tempo que contém um manancial de preciosa informação para os leitores e estudiosos europeus.

The telecommunications industry is highly competitive, as operators engage in fierce attacks, especially in bundled services, to acquire new customers originating high churn rate. The objective of this paper is to gain a comprehensive understanding of the factors influencing the switching of operators for bundled services among telecom operators. The paper includes a quantitative study with 3,004 customers utilizing bundled services from a Portuguese telecom operator. Employing covariance-based structural equation modeling and logit regression, the research shows that internet service, television service, and the service provided by the contact center exert the greatest impact on loyalty to the operator. In contrast, landline service has an insignificant effect, while loyalty has a negative influence on customer churn. This study offers telecommunications managers insights for identifying the main factors to retain customers and curbing customer defection. Additionally, it provides a framework for assessing customer experience within bundled telecom services, which is useful for researchers, managers and marketing practitioners alike.

The goal of this article is to analyse the relationship between rental
income and capitalisation rates when real estate value is assessed in parishes of the
Lisbon and Porto municipalities. Based on housing market values in euros per square
metre during the 2006-2009 period, the income approach was used to compare the two
main types of apartments (i.e. B2, or two-bedroom, and B1, or one-bedroom) in Lisbon and
Porto. We used the capital asset pricing model to calculate the risk measure. The cluster
analysis was used to group the Lisbon and Porto parishes according to their rental income
and capitalisation rates. Regressions were used to model both geographical markets.
Clear differences were found between Porto and Lisbon, the results being more robust for
the Porto municipality in regard to B2 apartments. Moreover, rental income is inversely
proportional to capitalisation rates for B1 apartments for Porto parishes, which means that
there is an initial overinvestment.

Proximity to green spaces has been shown to be beneficial to several cardiovascular outcomes in urban spaces. Few studies, however, have analyzed the relationship between these outcomes and green space or land cover uses in low–medium income megacities, where the consequences of rapid and inordinate urbanization impose several health hazards. This study used a subgroup of the dataset from The Brazilian Longitudinal Study of Adult Health ELSA-BRASIL (n = 3418) to identify the correlation between the medical diagnosis of hypertension and green spaces in the megacity of São Paulo. Land cover classification was performed based on the random forest algorithm using geometrically corrected aerial photography (orthophoto). Three different indicators of exposure to green spaces were used: number of street trees, land cover and number of parks within 1 km. We used logistic regression models to obtain the association of the metrics exposure and health outcomes. The number of street trees in the regional governments (OR = 0.937 and number of parks within 1 km (OR = 0.876) were inversely associated with a diagnosis of hypertension. Sixty-three percent of the population had no parks within 1 km of their residence. Our data indicate the need to encourage large-scale street tree planting and increase the number of qualified parks in megacities.

Enterohaemorrhagic Escherichia coli (EHEC) and enteropathogenic E coli (EPEC) translocate, dozens of type III secretion system effectors, including the WxxxE effectors Map, EspM and EspT that activate Rho GTPases. While map, which is carried on the LEE pathogenicity island, is absolutely conserved among EPEC and EHEC strains, the prevalence of espM and espT is not known. Here we report the results of a large screen aimed at determining the prevalence of esPM and espT among clinical EPEC and EHEC isolates. the results suggest that espM, detected in 51% of the tested strains, is more commonly found in EPEC and EHEC serogroups that are linked to severe human infections. in contrast, espT was absent from all the EHEC isolates and was found in only 1.8% of the tested EPEC strains. Further characterization of the virulence gene repertoire of the espT-positive strains led to the identification of a new zeta 2 intimin variant. All the espT-positive strains but two contained the tccP gene. espT was first found in Citrobacter rodentium and later in silico in EPEC E110019, which is of particular interest as this strain was responsible for a particularly severe diarrhoeal outbreak in Finland in 1987 that affected 650 individuals in a school complex and an additional 137 associated household members. Comparing the protein sequences of EspT to that of E110019 showed a high level of conservation, with only three strains encoding EspT that differed in 6 amino acids. At present, it is not clear why espT is so rare, and what impact EspM and EspT have on EPEC and EHEC infection. ; Spanish Ministry of Education and Science ; Spanish Ministry of Health and Consumer Affairs [Fondo de Investigacion Sanitaria, Spanish Network for the Research in Infectious Diseases (REIPI) ; Autonomous Government of Galicia ; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) ; Programa de Apoio a Nucleos de Excelencia ; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) ; MRC ; Wellcome Trust ; Univ Santiago de Compostela, Fac Vet, Dept Microbiol & Parasitol, Lab Referencia E Coli, Lugo, Spain ; Univ London Imperial Coll Sci Technol & Med, Div Cell & Mol Biol, Ctr Mol Microbiol & Infect, London SW7 2AZ, England ; Universidade Federal de São Paulo, Dept Microbiol Imunol & Parasitol, São Paulo, Brazil ; Complexo Hos Xeral Calde, Unidade Microbiol Clin, Lugo, Spain ; Universidade Federal de São Paulo, Dept Microbiol Imunol & Parasitol, São Paulo, Brazil ; Spanish Ministry of Health and Consumer Affairs [Fondo de Investigacion Sanitaria, Spanish Network for the Research in Infectious Diseases (REIPI): RD06/0008-10181 ; Spanish Ministry of Education and Science: AGL-200802129 ; Autonomous Government of Galicia: PGIDIT065TAL26101P ; Autonomous Government of Galicia: 07MRU036261PR ; FAPESP: 08/53812-4 ; Web of Science
