Review Citation - WoS: 171Citation - Scopus: 210A Comprehensive Review of the Novel Weighting Methods for Multi-Criteria Decision-Making(MDPI, 2023-05-11) Abacıoğlu, Seda; Ayan, Büşra; Basilio, Marcio PereiraIn the realm of multi-criteria decision-making (MCDM) problems, the selection of a weighting method holds a critical role. Researchers from diverse fields have consistently employed MCDM techniques, utilizing both traditional and novel methods to enhance the discipline. Acknowledging the significance of staying abreast of such methodological developments, this study endeavors to contribute to the field through a comprehensive review of several novel weighting-based methods: CILOS, IDOCRIW, FUCOM, LBWA, SAPEVO-M, and MEREC. Each method is scrutinized in terms of its characteristics and steps while also drawing upon publications extracted from the Web of Science (WoS) and Scopus databases. Through bibliometric and content analyses, this study delves into the trend, research components (sources, authors, countries, and affiliations), application areas, fuzzy implementations, hybrid studies (use of other weighting and/or ranking methods), and application tools for these methods. The findings of this review offer an insightful portrayal of the applications of each novel weighting method, thereby contributing valuable knowledge for researchers and practitioners within the field of MCDM.Article Citation - WoS: 51Citation - Scopus: 96Blockchain Technology and Sustainability in Supply Chains and a Closer Look at Different Industries: a Mixed Method Approach(MDPI, 2022-12-08) Güner, Elif; Ayan, Büsra; Son-Turan, SemenBackground: This study presents a comprehensive review of blockchain technology with a sustainability orientation in supply chains and logistics. Methods: The publications are extracted from the Scopus and Web of Science databases, comprising 552 publications between 2017 and 2022. Several bibliometric laws and techniques, namely three-field analysis, Bradford’s Law, Lotka’s Law, and thematic maps, are applied in R with the bibliometrix package. Content analysis is also carried out based on 185 publications to appreciate the industry-based view of the field. Results: The bibliometric results indicate that this field is on the rise. Authors, sources, affiliations, countries, keywords, and their relationships are also addressed. The findings of the content analysis and thematic maps reveal that some of the most highlighted themes in the literature include traceability, COVID-19, the internet of things, and Industry 4.0. The most popular industry in this field is discovered to be food and agriculture. Conclusions: This paper contributes to the still relatively scarce literature on how blockchain technology fosters sustainable supply chains and logistics, providing a closer look at blockchain use, methodologies, and future directions for different industries concerning food, agriculture, fashion, textile and apparel, manufacturing, automotive, maritime and shipping, healthcare and pharmaceutical, mining and mineral, and energy. © 2022 by the authors.Article Citation - WoS: 10Citation - Scopus: 27Fostering Equality in Education: the Blockchain Business Model for Higher Education (bbm-He)(MDPI, 2022-03-03) Turan, S. Semen; Son-Turan, SemenThis paper seeks to address which business model in higher education that fosters SDG 4, is adequate for the post-pandemic period. To that end, it introduces the “Blockchain Business Model for Higher Education” (BBM-HE) and a transformed business model canvas framework based on existing literature, concepts, theories and findings relating to most of the pressing issues in higher education from the present study. To determine these issues, secondary data is used in the qualitative research design by applying inductive content analysis techniques to online reports. The originality of this study lies in the “adaptive” perspective to the requirements of the post-pandemic higher education landscape, which consists of modifications to the core elements of higher education, the integration of blockchain technology into the entire system, and a stronger approach to sustainability practice through sustainability tokens. The envisaged model sets out to provide a roadmap for all stakeholders, but most importantly, “decentralized” higher education institutions of the future and the “employable skills-seeking” proactive students all over the world, as opposed to the former “solely degree-focused and affluent” consumers of educational offerings. This study contributes to higher education literature in terms of business models, blockchains, pandemics, and sustainability.Article Citation - WoS: 8Citation - Scopus: 9Corporate Social Responsibility Disclosure on the Websites of Coffee Chains in Turkey(Emerald, 2021-08-13) Tosun, PetekPurpose – Coffee is among the primary products that attract the public attention to the social andenvironmental responsibilities of companies. Coffee shops have a big carbon footprint because of their dailyoperations. With the rising consciousness about sustainability in developing countries, online disclosure ofcorporate social responsibility (CSR) is becoming increasingly important for not only multinational but alsolocal coffee chains. The purpose of this study is to analyze the extent to which coffee chains include CSR ontheir websites.Design/methodology/approach – Turkey, which is a large emerging economy with an expandingcoffee chain market, is selected as the research context. The CSR disclosure on the websites of coffee chains isexamined by content analysis according to CSR dimensions. A sample of 27 coffee chains with more than tenstores is included in the analysis.Findings – Foreign coffee chains disclose more information on the environment and fair trade than localcoffee chains. On the other hand, CSR content in websites of foreign and local coffee chains does not differsignificantly in human resources and community dimensions. Foreign coffee chains have comparativelylonger brand history, more rooted brands and larger networks than local coffee chains.Originality/value – To the best of the author’s knowledge, this study is the first that used a contentanalysis about CSR on the websites of coffee chains in Turkey. Findings contribute to the understanding ofCSR disclosure in the coffee chain industry and can be beneficial for researchers and managers in otheremerging markets.Keywords Marketing, Turkey, Emerging markets, CSR, Corporate social responsibility,Coffee chainsPaper type Research paperArticle Citation - WoS: 20Citation - Scopus: 24Voluntary Simplicity: a Content Analysis of Consumer Comments(Emerald, 2021-06-09) Tosun, Petek; Selime Sezgin; Sezgin, SelimePurpose -The voluntary simplification (VS) movement has stemmed from Western societies and gained momentum in the 1980s, but the trend has failed to become a primary perspective for most consumers. The accompanying concepts of conscious consumption, minimalism and accepting that sometimes “less is more” are still vivid in the digital era. The purpose of this study is to provide a deep and recent understanding of the consumer comments about minimalism in Turkey and examine their associations with the prominent themes in the VS literature.Design/methodology/approach -Consumer comments posted on online platforms were analyzed by content analysis and word frequency analysis.Findings -Consumer comments were in parallel to the themes in the VS literature and were classified under personal growth, material simplicity, sustainability, proper technology usage and self-sufficiency categories. Personal growth, material simplicity and sustainability were the first three dimensions mentioned. The prominent sub-themes that emerge from data were psychological well-being, inner peace, freedom, meaningful experiences and getting rid of belongings. A word frequency analysis pointed out that “life” and “owning” were the evident words in the personal growth category, “purchasing things” were mostly mentioned in the material simplicity category and “plastic litter” and “excessive consumption” were the prominent concerns in the sustainability category.Originality/value -VS required further research in different national contexts. Besides, an analysis of the dimensions of VS was needed. This study contributes by providing recent and rich findings from a developing country, connecting them with the VS themes in the literature and suggesting a conceptual framework enriched by sub-themes that emerged from data.
