Recycling post-consumer plastics in Santa Ana, Costa Rica.
No full textCosta Rica currently lacks post-consumer plastic recycling, due primarily to the fact that there is no washing process in practice; thus dirt and contaminants adhered to the plastics cannot be removed and will damage processing equipment and devalue the resulting secondary plastics. This project, submitted to el Centro de Investigaciones en Contaminacion Ambiental (CICA), analyzes each phase of the recycling process and provides recommendations for the implementation of a pilot post-consumer plastics recycling program in Santa Ana, Costa Rica

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Surgical Treatment of Benign Tracheal Stenosis in Adults
No full textBenign tracheal stenosis is responsible for considerable morbidity, and it is difficult to treat. Our objective is to present the results of surgical treatment. This was a retrospective chart review from the tertiary care center on Head and Neck Surgery in Hospital Ana Costa. We performed a retrospective review of 19 adult patients who underwent circumferential tracheal resection with end-to-end anastomosis from 1997 to 2003. Seventeen cases were caused by prolonged endotracheal intubation and tracheotomy; whereas, an invasive papillary thyroid carcinoma occurred in the other two. A minimum follow-up period of 12 months was considered for the final evaluation of the results. The patient ages varied from 18 to 70 years (median, 29 years). There were 16 men. In 6 patients, a T-shaped tube was kept in place because of extensive disease. The stenosis distance to the vocal folds varied from 11 to 22 mm. All the patients presented grades III or IV of narrowing. Four to eight rings were resected. The sleeve resection gave 89.5% success: one failure and one death. The success rate of tracheal resection with end-to-end anastomosis was 89.5%.Univ Fed Sao Paulo, Escola Paulista Med, Sao Paulo, BrazilHosp Heliopolis, HOSPHLEL, Postgrad Course Hlth Sci, Sao Paulo, BrazilHosp Ana Costa, Dept Head, Santos, SP, BrazilHosp Ana Costa, Dept Neck Surg, Santos, SP, BrazilIrmandade Santa Casa Misericordia Santos, Santos, SP, BrazilUniv Fed Sao Paulo, Escola Paulista Med, Sao Paulo, BrazilWeb of Scienc
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
