A inovação é considerada pelos economistas como fator determinante para o crescimento económico e social sustentável. No contexto da atual economia, global e marcada por uma profunda crise, torna-se imperativo compreender os padrões de inovação para suportar melhores políticas e respostas aos desafios que se impõem. Este entendimento conduz à ilação de que os desvios significativos no crescimento económico observado entre diferentes regiões são também explicados por diferenças espaciais nos padrões de inovação. Na sequência do exposto tem-se assistido a um renovado e crescente interesse no estudo da inovação numa perspetiva territorial e a uma crescente produção e disponibilização de dados para estudo e compreensão das suas dinâmicas. O objectivo principal da presente dissertação é demonstrar a utilidade de uma técnica de Data Mining, a rede neuronal Self Organizing Map, na exploração destes dados para estudo da inovação. Em concreto pretende-se demonstrar a capacidade desta técnica tanto para identificar perfis regionais de inovação bem como para visualizar a evolução desses perfis no tempo num mapa topológico virtual, o espaço de atributos do SOM, por comparação com um mapa geográfico. Foram utilizados dados Euronext relativos a 236 regiões europeias para os anos compreendidos entre 2003 e 2009. O Self Organizing Map foi construído com base no GeoSOM, software desenvolvido pelo Instituto Superior de Estatística e Gestão de Informação. Os resultados obtidos permitem demonstrar a utilidade desta técnica na visualização dos padrões de inovação das regiões europeias no espaço e no tempo.

The aim of the present study was to outline the serological profile of hepatitis C among blood donors seen at the Uberaba Regional Blood Center, Hemominas Foundation, over the last 14 years. The frequency of hepatitis C was compared between first-time and repeat donors and the epidemiological characteristics of those with positive and indeterminate ELISA anti-HCV (third and fourth generation) were analyzed based on the donor histories kept in the archives of the Uberaba Regional Blood Center. The serological ineligibility rate was 0.3%, with higher prevalence in the group of first-time donors. We did not find any significant differences regarding age, skin color, marital status or place of residence between eligible and ineligible donors; however, the frequency of positive serology was higher among men. The lower (0.3%) rate of ineligibility due to hepatitis C that was observed at the Uberaba Regional Blood Center, in relation to most Brazilian blood centers, is probably due to the large number of repeat donors (83.3%). This reinforces the importance of achieving donor commitment for increasing transfusion safety.

INTRODUCÃO: Estudo retrospectivo com o objetivo de avaliar a prevalência e fatores associados à soropositividade para o HTLV-1/2, no período de 1995 a 2008, no Hemocentro Regional de Uberaba e descrever os doadores soropositivos quanto ao gênero, idade, estado civil, cor de pele e procedência. MÉTODOS: Foram realizados análise estatística descritiva, testes qui-quadrado e odds ratio para comparação de proporções e gráfico de dispersão com coeficiente de correlação linear. RESULTADOS: Dentre x doadores testados, foi encontrada a prevalência de sorologia positiva para o HTLV de 0,02% e indeterminada de 0,09%. Houve uma redução significativa da sorologia positiva para HTLV, no período de 2002 a 2008, em comparação ao período de 1995 a 2001. Dentre os soropositivos, observou predomínio significante no gênero feminino. CONCLUSÕES: Imputamos a queda gradativa de soropositividade no período à exclusão permanente dos doadores de repetição soropositivos e ao aprimoramento dos métodos de triagem clínica e dos testes sorológicos ao longo dos anos com reflexos positivos na segurança transfusional.

INTRODUCTION: A retrospective study was conducted to assess the occurrence of blood donations that were ineligible due to Chagas disease infection from 1995 to 2009 at the Uberaba Regional Blood Center (HRU), Brazil, verify the tendency of this ineligibility, and describe the epidemiologic profile of the donors. METHODS: Retrospective studies of serological ineligibility due to Chagas disease, statistical analysis by means of the chi-square test and odds ratio, study of the tendencies using a dispersion graph and the linear correlation coefficient (r) were performed. RESULTS: In the period under study, a 0.2% serum prevalence of ineligibility due to Chagas disease was found, with a significant drop in ineligible donations from 2001 to 2009. Among the serum positive-donors, there was a significant predominance among those aged 30 years or above and non-single individuals. CONCLUSIONS: The results show a rate of occurrence that is lower than that described in literature, as well as a progressive drop during the 15 years under assessment. Such results are a consequence of systematic combat of the vector since the 70s and the progressive and consistent increase of returning donors, resulting in a drop of the contamination risk factor by means of blood transfusion and in the improvement of the quality of hemotherapy practices in the HRU.

INTRODUCTION: Little information regarding hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among Brazilian female prisoners exists. This study investigated the prevalence and risk factors associated with HBV and HCV infections and identified viral genotypes among female prisoners in Goiás, Central Brazil. METHODS: Women incarcerated in the largest prison in the State of Goiás were invited to participate in the study. All female prisoners were interviewed and tested for the detection of hepatitis B surface antigen (HBsAg), antibodies against HBsAg (anti-HBs), against hepatitis B core antigen (anti-HBc), and antibody against HCV (anti-HCV) by ELISA. HBsAg and anti-HCV positive samples were tested for HBV DNA and HCV RNA and genotyped, respectively. RESULTS: Participants (n=148; 98.6%) completed the study with an overall HBV prevalence of 18.9%. Age >30 years, a low education level, sex with a sexually transmitted diseases carrier, and a male sexual partner serving in the same penitentiary were associated with HBV infections. Only 24% of the women were anti-HBs positive suggesting previous HBV vaccination. Nine female prisoners (6.1%) were anti-HCV positive. Age >40 years, injecting drug use and length of incarceration were statistically associated with anti-HCV antibodies. Five samples were HCV RNA positive and classified as genotypes 1 (subtypes 1a; n=3 and 1b; n=1) and 3 (subtype 3a; n=1). The HBsAg-reactive sample was HBV DNA positive and genotype A. CONCLUSIONS: These findings highlight the necessity of public policies to control hepatitis B and C infections and emphasize the importance of hepatitis B vaccination in prison environments.

The emergence of the so-called “European Paradox” shows that R&D investment is not maximally effective and that increasing the scale of public R&D expenditures is not sufficient to generate employment and sustained economic growth. Increasing Governmental R&D Investment is far from being a “panacea” for stagnant growth. It is worth noting that Government R&D Investment does not have a statistically significant impact on employment, indicating the need to assess the trade-offs of policies that could lead to significant increases in government expenditure. Surprisingly, Governmental R&D Employment does not contribute to “mass-market” employment, despite its quite important role in reducing Youth-Unemployment. Despite the negative side-effects of Governmental R&D Employment on both GVA and GDP, University R&D Employment appears to have a quite important role in reducing Unemployment, especially Youth-Unemployment, while it also does not have a downside in terms of economic growth. Technological Capacity enhancement is the most effective instrument for reducing Unemployment and is a policy without any downside regarding sustainable economical development. In terms of wider policy implications, the results reinforce the idea that European Commission Research and Innovation policies must be restructured, shifting from a transnational framework to a more localised, measurable and operational approach.

Introduction: In Brazil, hantavirus cardiopulmonary syndrome (HCPS) has a high lethality rate that varies by region. This study aimed to identify the risk factors associated with fatal hantavirosis. Methods: This study was a case-control study that included all laboratory confirmed cases of hantavirosis. The cases were stratified by the different Brazilian regions using data from the Notifiable Diseases Information System. “Cases” were patients who progressed to death, whereas “controls” were patients who were cured. The odds ratio (OR) and the adjusted OR were calculated. Results: Overall, 158 cases and 281 controls were included in this study. In the Midwest region, the cases were 60% less likely to present with flank pain, and the time between the beginning of symptoms and death was shorter than the time between the beginning of symptoms and a cure. In the Southeast region, the cases were 60% less likely to present with thrombocytopenia or reside in rural areas compared to those who progressed to a cure. Additionally, the cases sought medical assistance, notification and investigation more quickly than the controls. In the Southern region, the cases that died were 70% less likely to be male compared to the controls. Conclusions: HCPS manifests with nonspecific symptoms, and there are few published studies related to the condition, so determining a patient's therapeutic strategy is difficult. This study presents findings from different Brazilian regions and highlights the need for further investigations to improve comprehension about regional risk factors associated with hantavirosis and to reduce morbimortality.

The hegemonic definition of Modernism has been subjected to an intense critical revision process that began several decades ago. This process has contributed to the significant broadening of the modernist canon by challenging its primal essentialist assumptions and formalist interpretations in the fields of both the visual arts and architecture. This conference aims to further expand this revision, as it seeks to discuss the notion of “Southern Modernisms” by considering the hypothesis that regional appropriations, both in Southern Europe and the Southern hemisphere, entailed important critical stances that have remained unseen or poorly explored by art and architectural historians. In association with the Southern Modernisms research project (FCT – EXPL/CPC-HAT/0191/2013), we want to consider the entrenchment of southern modernisms in popular culture (folk art and vernacular architecture) as anticipating some of the premises of what would later become known as critical regionalism. It is therefore our purpose to explore a research path that runs parallel to key claims on modernism’s intertwinement with bourgeois society and mass culture, by questioning the idea that an aesthetically significant regionalism – one that resists to the colonization of international styles and is supported by critical awareness – occurred only in the field of architecture, and can only be represented as a postmodernist turn.

INTRODUCTION: Occult hepatitis B infection (OBI) is considered to be one of the major risks for patients suffering from end-stage renal disease (ESRD) on regular hemodialysis (HD) and patients with chronic hepatitis C virus (HCV) infection. This study compared the prevalence of OBI among these two high-risk groups in the Suez Canal region, Northeastern Egypt, to obtain a better national overview of the magnitude of OBI in this region. METHODS: Serum samples were collected from 165 HD patients and 210 chronic HCV-infected patients. Anti-HCV antibody, hepatitis B surface antigen (HBsAg), total hepatitis B core (anti-HBc) antibody, and hepatitis B surface antibody (anti-HBs) were detected by enzyme-linked immunosorbent assay (ELISA). HCV RNA was detected using a quantitative real-time RT-PCR assay, and HBV was detected using a nested PCR. RESULTS: All patients were negative for HBsAg. A total of 49.1% and 25.2% of the patients in the HD and HCV groups, respectively, were anti-HBc-positive. In addition, more anti-HBs-positive patients were detected in the HD group compared to the HCV group (52.1% and 11.4%, respectively). Three cases were positive for HBV DNA in the HD group, while eighteen positive cases were detected in the HCV group. Both study groups showed significant differences in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level as well as anti-HBc, anti-HBs and HBV-DNA positivity. CONCLUSIONS: OBI was more prevalent among chronic HCV patients than HD patients in the Suez Canal region, Egypt, with rates of 8.5% and 1.8%, respectively. However, more precise assessment of this infection requires regular patient follow-up using HBV DNA detection methods.

A dieta regional de Manaus foi avaliada nutricionalmente por meio da análise química e percentual de adequação, tomando-se como referencial os padrões da National Academy of Science (19Ô9). A dieta foi elaborada utilizando-se os dados de Shrimpton & Giugliano (1979), para famílias com rendimentos de até dois salários mínimos mensais e preparadae de acordo com as técnicas culinárias habitualmente utilizadas pela população. Doe resultados obtidos, observou-se um déficit calorico de 54,3% para o homem adulto e 13,4% para a mulher adulta. Pas 1906 Kcal totale, os glicídios contribuíram com 60%, lipídios 20% e proteínas 20%. Quantitativamente, as proteínas estavam em níveis adequados, embora parte delas pudessem estar eendo utilizadas com finalidade energética. Dos minerais, o cálcio estava mais deficiente com um percentual de adequação da ordem de 50%. 0 ferro mostrou-se deficiente para a mulher adulta quando comparado com as necessidades recomendadae. Em relação ao teor de retino! proveniente do B-caroteno da dieta, o percentual foi de 12,6% e 15,0% respectivamente para homem e mulher. De acordo com os dados obtidos, concluiu-se que a dieta não atende às recomendações preconizadas para a maioria dos nutrientes estudados.

Foi estudada a biodisponibilidade de zinco em ratos recebendo uma dieta regional de Manaus, AM. A dieta foi elaborada segundo os dados de SHRIMPTON & GIUGLIANO, (1979) para famílias com rendimentos inferiores a 2 salários mínimos. O ensaio biológico com ratos da linhagem Wistar se baseou inicialmente, na depleção de zinco e vitamina A na lactação, adaptação dos filhotes com a dieta regional por 7 dias e período de repleção onde se realizou a suplementação com zinco de acordo com as recomendações do "COMMITTEE ON LABORATORY ANIMAL DIETS" (1979). Os resultados nos permitiram concluir que a quantidade de zinco presente na dieta, avaliada pelos parâmetros de medida de biodisponibilidade de zinco como crescimento, concentração nos órgãos e de enzima zinco dependente, foi utilizada adequadamente pelos animais, provavelmente pelos fatores promotores da dieta.
