Preliminary epidemiological features of kiwifruit skin pitting agent: Cadophora luteo-olivacea (J.F.H. Beyma) T.C. Harr. & McNew
No full textDuring the last 20 years, skin pitting symptoms, caused by Cadophora luteo-olivacea, were detected in packaging houses. Hence, there is a need to investigate the pathogenicity of this fungus, which is able to afflict kiwifruits during the postharvest phase. The study was conducted by linking different experiments conducted in vitro, in vivo, and in kiwifruit orchards. By in vitro assays, the influence of temperature and kiwifruit ripeness was evaluated on the pathogen growth. In vivo assays were conducted by artificially spraying the pathogen inoculum on kiwifruit and storing for 5 months at 0°C. Fruit were bagged in the field, from July to October, and stored 5 months at 0°C in normal refrigeration. After a shelf-life period (7 days at 20°C), the fruit phenological phase wherein the pathogen began its latency was verified. Results showed a higher ability of the pathogen to grow at 20°C with enhanced aggressiveness in under-ripe kiwifruits. Field experiment results indicated that kiwifruit bagged in July were less susceptible to skin pitting symptoms after storage. Finally, from these results, we can assert that field and storage management strategies should be strictly connected to control C. luteo-olivacea development
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
