Migration studies of chloropropanols from paperboard packaging in contact with foodstuffs
No full textThe food processing of acid hydrolyzed vegetable protein (HVP) results in the chlorination of residual lipids to form chloropropanols. 3-chloro-1,2-propanediol (3-monochloropropane-1,2-diol; 3-MCPD), and 1,3-dichloro-2-propanol (1,3-DCP), are the most common chloropropanols found in HVP foods and also soy sauces. The manufacturing process of paperboard food packaging may also produce chloropropanols. 3-MCPD and 1,3-DCP can be found in paperboard when wet-strength resins made with epichlorohydrin are used. 1,3-DCP had been determined to be carcinogenic in rats and mice. 3-MCPD was a suspected carcinogen , and has recently been moving towards classification as a carcinogen. The European (EU) Commission and the US Food and Drug Administration (US FDA) have set maximum levels in food and food paperboard packaging for 3-MCPD and 1,3-DCP. In October 2010, 3-MCPD and 1,3-DCP were added to the California Proposition 65 list of compounds known to State to cause cancer. In this investigation, migration studies were conducted to measure 3-MCPD and 1,3-DCP migration into food simulants from the food contact side of polyethylene extrusion-coated paperboard beverage cartons, and also total immersion extractions of both polyethylene extrusion-coated and uncoated paperboard. It is shown that 3-MCPD, found at levels far above the regulatory limits for food packaging, does not migrate at a significant amount through the polyethylene extrusion-coated food contact surface of the paperboard. The aqueous extractions of the entire paperboard and food contact side extractions with aqueous and acidic food simulants were performed using US FDA and EU Commission standard and accelerated migration testing protocols. In these migration studies, an EU standard method for cold water total immersion extractions was compared to migration cell extractions to measure the chloropropanols migration into food simulant solvents from the entire paperboard and the isolated food contact side of polyethylene extrusion-coated paperboard beverage cartons. This research demonstrates that polyethylene food contact coated film can function as a barrier to the migration of 3-MCPD into the food packaged in a polyethylene extrusion-coated paperboard engineered for that purpose.Ph.D.Includes bibliographical referencesIncludes vitaby Gregory V.

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
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
