Molecular markers-based analysis for crop germplasm preservation
No full textThe present paper aims to highlight the potential impact, as well as possible drawbacks, of the application of DNA marker technology to crop germplasm preservation. Some of the issues related to crop management and use, which can be addressed by using information derived from DNA markers, are discussed with reference to case-studies

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
Detection of minced beef adulteration with turkey meat by UV-vis, NIR and MIR spectroscopy
No full textThe aim of this work was to investigate the potential of UV-visible (UV-vis), near infrared (NIR) and mid infrared (MIR) spectroscopy, coupled with chemometric techniques, to detect minced beef adulteration with turkey meat. Besides 44 minced meat samples of pure bovine and 44 of pure turkey, 154 mixtures of minced beef adulterated with turkey meat in the range 5-50% (w/w) were prepared and analyzed. The spectral data, standardized by different pre-treatments, were processed, separately or fused, using Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), and Partial Least Squares (PLS) regression. Moreover, a variable selection method was performed before classification and regression analysis. Among the three spectroscopic techniques, comparing the PLS models in terms of errors in prediction (RMSEP), the best results were obtained with NIR and MIR spectroscopy, whereas the UV-vis results were less satisfactory. Finally, combining information from UV-vis, NIR and MIR spectroscopy improved the overall results
