Exploring and exploiting anthocyanins for human needs: potato as a research case study
Full text linkAnthocyanins are a group of polyphenolic water-soluble pigments, largely distributed in the plant kingdom. Being natural pigments with a health-promoting bioactivity, there is an increasing interest for their application in food and drugs industry. The increasing in anthocyanins production is an enticing achievement of industries. In the first part of this review, we highlight key concepts related to the biochemistry, biological function and genetics of these important pigments in the potato. We chose this crop because it displays a valuable anthocyanin chemical diversity and it is also highly amenable to various biotechnological applications. In this latter regard, we present and briefly discuss the potential of cell cultures as a suitable method for the production of highly decorated anthocyanins. The final message of this review is to underline the impact of bio-factories as a customizable and sustainable strategy for anthocyanin production and their high potential in industrial and medical applications
HUGO MÜNSTERBERG: THE PROJECT OF AN IDEALISTIC PHILOSOPHICAL FOUNDATION OF PHYSIOLOGICAL PSYCHOLOGY

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
Introduction: towards a reconsideration of Neo-Kantianism
No full textAfter the demise of German Idealism, Neo-Kantianism flourished as the defining philosophical movement of Continental Europe from the 1860s until the Weimar Republic. This collection of new essays by distinguished scholars offers a fresh examination of the many and enduring contributions that Neo-Kantianism has made to a diverse range of philosophical subjects. The essays discuss classical figures and themes, including the Marburg and Southwestern Schools, Cohen, Cassirer, Rickert, and Natorp's psychology. In addition they examine lesser-known topics, including the Neo-Kantian influence on theory of law, Husserlian phenomenology, Simmel's study of Rembrandt, Cassirer's philosophy of science, Cohen's philosophy of religion in relation to Rawls and Habermas, and Rickert's theory of number. This rich exploration of a major philosophical movement will interest scholars and upper-level students of Kant, twentieth-century philosophy, continental philosophy, sociology, and psychology
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
