    Magnetic resonance in food science - meeting the challenge

    No full text
    In 1995, the first book devoted to the applications of magnetic resonance to food science was published. Many of the topics covered in that work are still present in the current special issue of this Magnetic Resonance in Chemistry: water in food, meat, imaging methods, analysis of liquids, electron spin resonance, online analysis, authentication and imaging. The basis of the techniques applied has remained the same, although there have been very significant improvements in the sophistication of the methodology. For example, pulse field gradient techniques have improved enormously, and much higher magnetic fields are available

    FoodOmics. The science for discovering

    No full text
    The term “FoodOmics” first popped up in the scientific literature around 2009. In the same year, the first International Conference on FoodOmics took place in Cesena. Probably neither us, as the scientific organizers of the conference, nor Alejandro Cifuentes, who first used the term in a scientific paper, thought that somany scientists would have been interested in the field. Since then, FoodOmics, like all the other Omics, rapidly evolved due to the development of novel tools and technologies. This iswitnessed by the many FoodOmics articles that have been published on scientific journals, and professor Cifuentes has been one of the invited speakers in the Second International Conference on FoodOmics, held in Cesena in 2011. At the end of 2012,we asked ourselves “is it timefor the third edition of the Conference?” What is new in this third edition? Themost important news is that we don't need to explain what FoodOmics is anymore, since everybody knows. And it is a big step ahead!Whatwe need nowis to share the possibility of the application of the FoodOmics concept (and techniques) to the different research fields. So, the subtitle of the Conference “A Science for Nutrition, Health and Wellness in the Post- Genomic Era” used in the first two editions was turned to “FoodOmics, the science for discovering” in 2013. The abstract book of the Conference, and this special issue of Food Research International, testify that the FoodOmics vision is a reality shared by many researchers. In this special issue of FRI dedicated to the Conference, critical reviews as well as descriptions of new approaches for use in the analysis and manipulation of food genomes, proteomes and glycomes are presented. The issue startswith three research papers each describing the use of themost recentNMR andMS instrumental advances to analyze in depth food metabolomes. These three articles are followed by a section of five papers investigating the process of food digestion – the digestome– and the fate of food constituents across it. The next article extends the field of applications to peptidomics and glycomics through the characterization of milk colostrum. The final section in this issue presents six articles facing the impact of food bioactive components from the nutritional, clinical and diagnostic sides. What about 2015? Difficult to say, even using “omics” techniques... One thing is certain: the field of FoodOmics will continue to grow in both application and scope and this will assist research to reshape our current understanding of the complex issues related to food, nutrition and health.We are planning the Fourth FoodOmics Conference, hoping to involve an increasing number of participants. At present, we wish to thank all Colleagues who contributed to the 2013 Conference, and to this special issue devoted to it

    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

    Full text link
    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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
