Escalating dose of tegafur combined with oral etoposide in metastatic gastric carcinoma.
Fifteen patients with advanced gastric cancer received orally etoposide 100 mg daily for 14 days and escalating doses of tegafur. The starting dose was 400 mg daily. The maximum tolerated dose of tegafur was identified at 850 mg daily. Unacceptable toxicity was seen at 1000 mg, and consisted of diarrhea, stomatitis and leukopenia. Two partial responses were seen at 800 mg daily. In conclusion, our data show that etoposide and tegafur can be safely administered in combination by the oral route
Have enteric infections a role in 5-fluorouracil-associated diarrhea?
In 16 advanced colorectal cancer patients with 5-fluorouracil-associated diarrhea, we evaluated the role of bacterial pathogens in the development of this adverse effect. Neither Clostridium difficile nor other pathogens were cultured from fecal specimens. These data seem to suggest that it is unlikely that intestinal infections have a role in the pathogenesis of 5FU-associated diarrhea
The socio-economic benefits of Earth Observation (EO): insights from the final users of EO services and applications in Italy
Earth observation (EO) is a strategic and fast-changing domain of the
space economy that increasingly contributes to the understanding, analysis
and management of different natural and societal aspects of Earth. A range
of socio-economic benefits may derive from the use of EO data. This
chapter aims to identify the benefits accrued by end users of EO services
and applications, on which there is scarce evidence in the literature. With
the objective of filling in this gap, the chapter relies on a survey distributed
to the end users of EO services in Italy, a country which is active along the
whole value chain of the space economy
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
