Textile waste in the context of the circular economy
No full textThe concept of a circular economy is built in opposition to the traditional linear model where raw materials are used, things are created from them, they are consumed and the leftovers are thrown away. This model relies on large quantities of cheap and accessible materials and energy sources. The textile sector is part of the economies meeting the requirements of the circular economy. What is the real place and importance of waste from textile production and their role for the circular economy, determine the relevance and arouse the interest of the authors in the research. The objective of this paper is to provide a comprehensive overview of the existing situation and to study the textile waste in the context of the circular economy. For the goal fulfillment we use the descriptive-analytical method - theoretical aspects of the studied scientific field are investigated on the basis of current literature research. The information collected is summarized and analyzed; systematic approach; analytical approach; study of the works of authors in the field; comparative analysis; method of observation; determination of relative shares. Current scientific research and economic aspects about textile waste in the context of the circular economy have been explored. The various author collectives work in the field of textile waste, its management and its connection with the circular economy. Research in the field of textiles shows the great importance and fundamental role of textile waste for the realization of the circular economy concept
Upcycling in the context of sustainability in the textile industry
No full textUpcycling represents a transformative process converting textile waste or disused textile products into new materials or goods of equal or superior quality, while enhancing both consumer utility and environmental benefits. This study examines upcycling within the framework of textile industry sustainability through a comprehensive descriptive-analytical methodology. Current theoretical foundations are investigated via systematic literature review, incorporating analytical evaluation, comparative assessment, and observational analysis of existing scholarly works in the field. The investigation reveals substantial existing research on textile upcycling’s role in sustainable development, providing valuable insights for identifying emerging scientific trends and potential future research directions. The synthesized findings contribute to a deeper understanding of upcycling applications and their implications for sustainable textile production systems
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
Sustainability of the European textile industry
No full textThe objective of this article is to study sustainability of the European textile industry. The descriptive-analytical method is used to fulfill the aim - the theoretical aspects of the researched scientific field are investigated on the basis of a current literature survey. The collected information is summarized and analyzed using a systematic approach; an analytical approach; a study of the works of authors in the field; a comparative analysis; an observational method; and the determination of relative shares. The textile industry in the context of the circular economy and the Union's policies should lead to improvements in the environmental performance of textile raw materials and materials, production, consumption, textile waste management, as well as their reduction, recycling, processing and environmental impact calculation. The sustainability of the textile industry can also be realized through the development and implementation of digitalization. Sustainability development of textile industry includes the three dimensions of sustainability: social, ecological and economic, which can be implemented in the context of the circular economy, digitalization and Sustainable Development Goals for the textile industry, in line with Europe 2030 policies. Keywords: sustainability, circular economy, digitalization, textile sector, European textile industry
