Editorial: Innovations and challenges in green and sustainable water purification and waste water management
Get PDFThis current issue covers the use of green adsorbents, green solvents, or any green processes and technologies for the purification of drinking water and wastewater. It addresses the research and innovations, as well as the engineering and management practices, for water purification and resource restoration and recovery, thus inspiring the new generation in respect to wastewater treatment and its management through green and sustainable methods
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
Optical and biological properties of metal-containing macromolecules
No full textOrganometallic macromolecular polymers and dendrimers constructed with various chromophores and antimicrobial species are attracting considerable attention. Interest in these materials stems from their exceptional properties and potential applications in the industry as biomedical and photoactive agents, as well as their use as sensors. Over the past few decades, the exponential growth of many new classes of metallo-macromolecules that address these issues has been illustrated. Metal-based antimicrobial macromolecules are rising due to the combination of the multiple interactions of the unique properties of metallic moieties and the effect of the bioactive species. Progress in the field of organometallic photoactive materials derives from their broad applications, including photonic switches and upconversion lasers, in addition to sensors and electronic devices. The aim of this inclusive review is to highlight the design and properties of several types of bioactive and drug delivery macromolecules containing metallic moieties as well as metallopolymers and dendrimers containing organic light-emitting diodes
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
