CoronaFatos: #56 - Tomei a vacina. E agora?
No full textFicha técnica: Apresentação: Ana Cristina Figueira e Gustavo Audi / Roteiro: Gabriel Fonseca / Produção: Valéria Mauro / Edição e Finalização: Marcelo Louro / Arte: Marcelo Vianna / Idealização: Canal Saúde - Fundação Oswaldo Cruz.Essa edição do CoronaFatos procura responder a uma pergunta que parece simples, mas acaba envolvendo diversas dúvidas de muitas pessoas. Tomei a vacina. E agora? O que esperar quando chega a sua vez de se imunizar e o que fazer depois desse esperado evento. Por que não se deve ficar com medo de reações adversas, a importância da segunda dose e por que ainda devemos continuar mantendo os cuidados por algum tempo, mesmo vacinados, são algumas das questões esclarecidas no programa. Além disso, esse episódio também aproveita para esclarecer de uma vez por todas por que não se deve ficar escolhendo qual marca de vacina tomar quando chega a vez. Ou seja, porque não se deve ser um “sommelier” de vacina
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Acetylcholinesterase as a biomarker of exposure to neurotoxic compounds in the clam Tapes philippinarum from the Lagoon of Venice
No full textMeasurement of acetylcholinesterase (AChE) is widely used as a biomarker of exposure to neurotoxic compounds in aquatic
environments. In the present study, AChE activity was monitored in the clam Tapes philippinarum in the Lagoon of Venice, with
the aim of evaluating the possible exposure of animals to neurotoxic compounds. Two sampling strategies were followed. In the
first case, temporal and spatial variations of AChE activity were measured in clams collected seasonally (from October 2003 to June
2004) in 3 sites of the Lagoon: Campalto (site 1), near a sewage treatment plant, Marghera (site 2), a highly polluted area, and Poveglia
(site 3), a reference site. The condition index (CI) of clams was also calculated. In the second case, AChE activity was measured
in clams collected at the end of seasonal samplings in 12 sites located throughout the Lagoon: areas licensed for clam farming (sites 5
to 11), nearby canals characterised by waste waters from agricultural areas (sites 4, 12, 13, 14), and a reference site outside the
Lagoon (site 15). Results revealed a significant reduction in AChE activity in clams from Marghera in October, January and April,
indicating their probable exposure to neurotoxic compounds originating in the industrial zone of Porto Marghera. A seasonal trend
in AChE activity was also observed, enzyme activity being higher in January and lower in June. Clams from Campalto generally had
higher CI values than those from Marghera and Poveglia. However, no particular correlation between AChE activity and CI was
found. Lastly, marked differences in AChE activity were recorded when comparing enzyme activity of clams from various sites in the
Lagoon of Venice with those of clams collected at site 15. Significant reductions in AChE activity were observed in animals collected
in both nearby canals and licensed areas, indicating the homogeneous spatial distribution of potentially neurotoxic compounds
throughout the Lagoon. It is probable that sediment mobilisation caused by clam harvesting and the passage of shipping plays
an important role in resuspension of persistent contaminants having neurotoxic activity
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
