Fotografia : a arte submetida à crítica

O presente trabalho consiste num estudo sobre as revistas Objectiva (1937-1947) e Foto Revista (1937-1939), estabelecendo-se como uma reflexão em torno da crítica de arte fotográfica. Na década de 1930, assistiu-se, em Portugal, a um interesse renovado pela fotografia (tida como) artística. O Estado Novo suportou regulares eventos neste domínio - são exemplos os Salões Nacionais de Arte Fotográfica, com início em 1932, que posteriormente tomaram contornos mais alargados, com o advento dos Salões Internacionais de Arte Fotográfica em 1937. Entretanto, a crítica de arte dedicada à fotografia ficara sem um suporte jornalístico. Contudo, em finais dos anos 30, o entusiasmo em torno da fotografia artística tomou contornos mais expressivos com a aproximação dos salões de foro internacional, o que levou ao ressurgimento de publicações periódicas dedicadas à fotografia. Depois de seis anos sem qualquer revista especializada neste domínio, assistese ao advento da Objectiva e Foto Revista, publicações mensais, as quais proporcionaram espaço e visibilidade para a crítica dedicada à fotografia artística. As duas publicações dedicaram-se, entre outras vertentes, à apreciação dos eventos mais significativos no território nacional, ao aconselhamento dos amadores fotográficos emergentes e à discussão dos temas mais pertinentes à época. Num período em que a produção artística fotográfica se encontrava, de um modo geral, dessincronizada do panorama internacional, e tendo em conta a conceção de crítica de arte como orientadora de tendências, importa conhecer as opções, entendimentos e proliferação de valores que esta promoveu, respeitantes à fotografia nacional (então) contemporânea.

Splenectomy in a patient with treatment-resistant visceral leishmaniasis: a case report

Visceral leishmaniasis (VL), also known as Kala-azar, is a systemic infection caused by a protozoan (Leishmania) and, in its classic form, is a serious illness associated with malnutrition, anemia, hepatosplenomegaly, infectious processes and coagulopathies. The effect of splenectomy in patients with visceral leishmaniasis is not well defined; however, it is known that the spleen is the largest reservoir of infected cells belonging to the reticulo endothelial system. Therefore, the surgical procedure is an option for the debulking of parasites, providing a cure for refractory VL and minimizing the complications of hypersplenism.

They bene oure frendes wyth there commoditez [...]"': uma retórica da amizade? Uma amizade retórica?"

Redigido c.1436, The Libel of English Policy, texto que integra o passo transcrito no título desta comunicação, foi já apresentado por Maria Laura Bettencourt Pires como um "[...] poema [...]", contendo "[...] possivelmente a mais antiga referência a Portugal na literatura inglesa." (Pires (ed.), 1981: 15). Salvaguardado o respeito devido às palavras da Professora Laura Pires, pensamos que, stricto sensu, o Libel pouco terá de "poema" (ou sequer de "literatura"), pese embora a sua importância documental para os Estudos Anglo-Portugueses e a própria história da política externa inglesa na primeira metade do séc. XV.

Genetic polymorphism for IFNγ +874T/A in patients with acute toxoplasmosis

INTRODUCTION: A single nucleotide polymorphism (SNP) in the gene encoding gamma interferon influences its production and is associated with severity of infectious diseases. This study aimed to evaluate the association of IFNγ+874T/A SNP with duration of disease, morbidity, and development of retinochoroiditis in acute toxoplasmosis. METHODS: A case-control study was conducted among 30 patients and 90 controls. RESULTS: Although statistical associations were not confirmed, A-allele was more common among retinochoroiditis cases and prolonged illness, while T-allele was more frequent in severe disease. CONCLUSIONS: Despite few cases, the results could indicate a relation between IFNγ+874T/A single nucleotide polymorphism and clinical manifestations of toxoplasmosis.

Atypical presentation of sporotrichosis: report of three cases

Sporotrichosis occurs after fungal implantation of Sporothrix spp. in the skin, and is the main subcutaneous mycosis in Latin America. Here we describe three atypical cases of the disease. The first case report an extra-cutaneous occurrence of the disease with joint infection; the second one describes a patient with bilateral lymphocutaneous form of sporotrichosis; and the third shows a zoonotic cutaneous case with the development of an erythema nodosum as a hypersensitivity reaction. These cases show the disease importance on the region and the necessity of fungal culture to the diagnosis confirmation.

Estudo experimental de um sistema BIPV/T-PCM

A União Europeia tem dado cada vez mais enfoque à eficiência energética nos edifícios e à sua capacidade de produção de energia, tendo lançado a directiva “Energy Performance of Buildings Directive” com o intuito de que até 31 de Dezembro de 2018 todos os edifícios novos sejam “nZEB-nearly Zero Energy Building”, o que significa que devem por um lado diminuir o seu consumo energético, aumentando a sua eficiência, e por outro lado produzir localmente e através de fontes de energias renováveis toda, ou quase toda, a energia de que necessitam. A presente tese está integrada no Projecto “Frame – Prefabricated systems (modules) for low-energy buildings: design, prototyping and testing” (Ref: PTDC/AURAQI-AQI/117782/2010) que está a ser desenvolvido na Unidade de Eficiência Energética do Laboratório Nacional de Energia e Geologia (LNEG). Neste trabalho é desenvolvido e analisado um sistema BIPV/T-PCM (Building Integrated Photovoltaic Thermal – Phase Change Materials) que engloba todo um novo conceito de captação, armazenamento e gestão da energia solar em fachadas. Este sistema é composto por um módulo fotovoltaico, uma bateria de PCM (Materiais de Mudança de Fase) e todo um sistema de fluxo de ar que permite a gestão da energia colectada e armazenada. Foi também desenvolvido teoricamente um código de gestão energética para a manipulação do sistema. O sistema em estudo apoia-se em três objectivos principais: aquecer no inverno; arrefecer no verão; e aumentar a eficiência do PV arrefecendo-o. Na sequência do trabalho realizado verificou-se que o conceito do sistema em estudo alcança alguns dos objectivos propostos, tendo ainda potencial para se continuar o seu desenvolvimento. O sistema em estudo é um sistema inovador, e como tal está a ser registada uma patente com base no conceito desenvolvido.

Trends and factors associated with dengue mortality and fatality in Brazil

AbstractINTRODUCTION:Studies that generate information that may reduce the dengue death risk are essential. This study analyzed time trends and risk factors for dengue mortality and fatality in Brazil from 2001 to 2011.METHODS:Time trends for dengue mortality and fatality rates were analyzed using simple linear regression. Associations between the dengue mortality and the case fatality rates and socioeconomic, demographic, and health care indicators at the municipality level were analyzed using negative binomial regression.RESULTS:The dengue hemorrhagic fever case fatality rate increased in Brazil from 2001 to 2011 (β=0.67; p=0.036), in patients aged 0-14 years (β=0.48; p=0.030) and in those aged ≥15 years (β=1.1; p<0.01). Factors associated with the dengue case fatality rate were the average income per capita (MRR=0.99; p=0.038) and the number of basic health units per population (MRR=0.89; p<0.001). Mortality rates increased from 2001 to 2011 (β=0.350; p=0.002).Factors associated with mortality were inequality (RR=1.02; p=0.001) high income per capita (MRR=0.99; p=0.005), and higher proportions of populations living in urban areas (MRR=1.01; p<0.001).CONCLUSIONS:The increases in the dengue mortality and case fatality rates and the associated socioeconomic and health care factors, suggest the need for structural and intersectoral investments to improve living conditions and to sustainably reduce these outcomes.

Epidemiological study of hepatitis B and C in a municipality with rural characteristics: Cássia dos Coqueiros, State of São Paulo, Brazil

Abstract: INTRODUCTION: Hepatitis B and C viral infections remain an important cause of global morbidity and mortality. Studies have been conducted in population groups of large cities, leaving gaps in the knowledge regarding the situation in small municipalities. We aimed to measure the prevalence of hepatitis B and C markers and presence of infection-associated factors. METHODS: All inhabitants of Cássia dos Coqueiros aged ≥18 years who agreed to participate in the research were included. We collected blood as well as information via a questionnaire between March 2011 and December 2013. Univariate and multivariate analyses were conducted. RESULTS: Among the 1,001 participants, 41 (4.1%) participants had a serological profile of hepatitis B viral exposure, and only one (0.1%) participant was considered a virus carrier. The frequency of isolated antibody to hepatitis B virus surface antigen (anti-HBs) markers was 17.8% for the overall population. In the multivariate analysis, hepatitis B virus (HBV) infection was associated with age, birth outside the State of São Paulo, history of hepatitis, ≥2 sexual partners in the last 6 months, and tattoos. Four (0.4%) participants had a serological profile of hepatitis C viral exposure. However, after confirmation using viral ribonucleic acid (RNA) evaluation, only one (0.1%) individual remained positive. CONCLUSIONS: The positivity rates for hepatitis B and C were low, despite greater sexual freedom and the recent emergence of illicit drugs, as observed by the health personnel working in Cássia dos Coqueiros.

Can body traits, other than wings, reflect the flight ability of Triatominae bugs?

Abstract: INTRODUCTION : Insects of the subfamily Triatominae are vectors of Trypanosoma cruzi , the Chagas disease parasite, and their flying behavior has epidemiological importance. The flying capacity is strikingly different across and within Triatominae species, as well as between sexes or individuals. Many Triatoma infestans individuals have wings but no flying muscles. In other Triatominae species, no clear relationships were found between wing length and flying behavior. If wing presence or size is not reflective of the flying behavior, which other parts of the body could be considered as reliable markers of this important function? METHODS : The genus Mepraia has exceptional characteristics with invariably wingless females and wingless or winged males. We calculated the porous surface exposed to odorant molecules to estimate the olfactory capacity of Mepraia spinolai . The head shape and thorax size were estimated using the geometric morphometric approach and traditional morphometric techniques, respectively. RESULTS : Alary polymorphism in M. spinolai was significantly associated with consistent modification of the thorax size, head shape, and notable change in the estimated olfactory capacity. The macropterous individuals had a larger olfactory surface and thorax size and significantly different head shape compared to those of the micropterous individuals. CONCLUSIONS: We concluded that these structural changes could be associated with the flying potential of Triatominae. Thus, morphological attributes not found on wings could help determine the likely flying potential of the bugs.

Epidemiology of infectious meningitis in the State of Amazonas, Brazil

INTRODUCTION: In the State of Amazonas, particularly in the capital Manaus, meningitis has affected populations of different cultures and social strata over the years. Bacterial meningitis is caused by several different species and represents a major issue of public health importance. The present study reports the meningitis case numbers with different etiologies in Amazonas from January 1976 to December 2012. METHODS: Since the 1970s, the (currently named) Tropical Medicine Foundation of Doutor Heitor Vieira Dourado [Fundação de Medicina Tropical Doutor Heitor Vieira Dourado (FMT-HVD)] has remained a reference center in Amazonas for the treatment of meningitis through the diagnosis and notification of cases and the confirmation of such cases using specific laboratory tests. RESULTS: The foundation has achieved coverage of over 90% of the state medical records for many years. Between 1990 and 2012, meningitis cases caused by Haemophilus influenzae decreased with the introduction of the H. influenzae vaccine. Meningococcal disease previously had a higher frequency of serogroup B disease, but starting in 2008, the detection of serogroup C increased gradually and has outpaced the detection of serogroup B. Recently, surveillance has improved the etiological definition of viral meningitis at FMT-HVD, with enteroviruses, Epstein-Barr virus (EBV) and varicella zoster virus (VZV) prevailing in this group of pathogens. With the advent of acquired immunodeficiency syndrome (AIDS), cryptococcal meningitis has become an important disease in Amazonas. Additionally, infectious meningitis is an important burden in the State of Amazonas. CONCLUSIONS: Changes in the epidemiological profile for the different etiology-defined cases are the result of continuous epidemiological surveillance and laboratory capacity improvements and control measures, such as Haemophilus influenzae vaccination.

A utilidade da aprendizagem criativa na aula de língua estrangeira

Este relatório surge no âmbito da minha Prática do Ensino Supervisionada e representa uma reflexão sobre a minha iniciação como professora de Inglês e de Francês no 3º ciclo do Ensino Básico e no Ensino Secundário. A reflexão teve como objeto o conceito de ‘aprendizagem criativa’ na teoria do ensino da língua estrangeira e a sua aplicação na prática letiva, nas duas escolas onde desenvolvi o meu estágio, a Escola Secundária de Sebastião da Gama e a Escola Básica do 2º e 3º Ciclos de Aranguez, ambas em Setúbal. Para além de uma tentativa de sistematização das abordagens teóricos, de modo a tornar a noção de ‘criatividade’ mais aplicável na prática da docência da língua estrangeira, a nossa reflexão procura evidenciar como e em que situações a aprendizagem se revela criativa e demonstra a sua utilidade para a aula de língua estrangeira.

Influence of employee volunteering on brand commitment

Purpose – The purpose of this paper is to explore the impact of corporate volunteering on employee bonding and to understand the barriers and motivation to participation in these events. In contrast to other studies the participants volunteer in their spare time without expecting any financial reward. Design/methodology/approach – Employees (n 3951) of a logistic company participated in the study based on an online questionnaire with 6 items and open questions. The employee sample was divided into 3 groups depending on the frequency of participation in volunteering events. Findings – Significant differences were found on bonding between the three groups. In addition, the relevance of control variables like gender, age and job level were obtained. Furthermore a moderation effect of motivation was found. The results were interpreted within the broader context that ties motivation theory, organizational identification and social exchange theory.
