Erratum: The C-terminal region of yeast ubiquitin-protein ligase Not4 mediates its cellular localization and stress response
No full textIn the originally published version of this manuscript, a citation and acknowledgement were omitted in error. A passage from the Methods section should read: 'The pNot4-GFP plasmid was obtained as previously described (Serafini 2004), briefly: inserting the EcoRI/SalI fragment. . . ' Instead of: 'The pNot4-GFP plasmid was obtained by inserting the EcoRI/SalI fragment. . . ' The acknowledgements should read: 'We thank Professor Roy Parker for kindly providing the pRP1155/CEN/LEU plasmid expressing a tagged version of Dcp2p with RFP (Dcp2p-RFP) and Dr Agnese Serafini for providing the pNot4-GFP plasmid expressing a tagged version of Not4 with GFP (Not4-GFP).'

Programmed cell death in the yeast Saccharomyces cerevisiae
No full textThe yeast Saccharomyces cerevisiae is one of the most studied model systems for molecular and cellular biology. In 1996, it became the first eukaryotic organism to have a completely sequenced genome (Dujon, 1996; Goffeau et al., 1996), which led to a number of valuable and widely accessed databases. Among its features is the short generation time (usually 90–120 minutes) and the ability to grow at various temperatures in relatively inexpensive media. Moreover, many of its genes are well characterized, thanks in part to its amenability to modifications such as gene disruption, gene marking, mutations, or gene-dosage modifications. Because of these advantageous features, it has become the model organism of choice for many investigators in fields ranging from basic biology to biomedical research
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
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
