    A Comprehensive Review of the Novel Weighting Methods for Multi-Criteria Decision-Making
    (MDPI, 2023-05-11) Abacıoğlu, Seda; Ayan, Büşra; Basilio, Marcio Pereira
    In 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.

    Blockchain 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, Semen
    Background: 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.

    Fostering Equality in Education: the Blockchain Business Model for Higher Education (bbm-He)
    (MDPI, 2022-03-03) Turan, S. Semen; Son-Turan, Semen
    This 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.

    Voluntary Simplicity: a Content Analysis of Consumer Comments
    (Emerald, 2021-06-09) Tosun, Petek; Selime Sezgin; Sezgin, Selime
    Purpose -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.

    Meat Substitutes in Sustainability Context: a Content Analysis of Consumer Attitudes
    (Routledge, 2020-10-29) Tosun, Petek; Sezgin, Selime; Uray, Nimet; Gürce, Merve Yanar; Yanar, Merve
    Food consumption affects the environment because it requires the usage of water, land, and oil resources. In particular, the consumption of red meat is associated with sustainability issues. Replacing meat with plant-based meat substitutes offers a useful way of reducing the burden that meat consumption places on the environment and dealing with issues regarding animal welfare. However, consumer acceptance of such products is low in some countries. The purpose of this paper is to clarify consumer attitudes toward meat substitutes and discuss them from a marketing perspective. The findings of this study, which are based on content analyses of web forums in Turkey, indicate that negative consumer perceptions can be categorized into three main dimensions: unhealthy, unusual, and tasteless. A marketing perceptive is used to dis- cuss the findings.

    Supervisor and Customer-Driven Stressors To Predict Silence and Voice Motives: Mediating and Moderating Roles of Anger and Self-Control
    (Taylor & Francis, 2020-07-02) Muhammad Kashif; Shanika Wijenayake; Merve Yanar Gürce; Tosun, Petek; Kashif, Muhammad; Gürce, Merve Yanar; Wijenayake, Shanika
    This study aims to investigate communicative deviance among front line employees (FLEs) as a consequence of supervisor and customer mistreatment. The emotion of anger as a mediator while self-control as a moderator is positioned to buffer the customer and supervisor aggression–>communicative deviance. The survey-based data from 284 Turkish FLEs demonstrate that abusive supervision triggers negative emotion of anger, resulting in deviant silence. A stronger support for self- control as a moderator to buffer the anger–deviant silence relationship is also found. The study uniquely integrates human emotions to investigate destructive work behaviors in a service context.

    Introduction To the Special Issue: the Leadership Imperative for Sustainability and Corporate Social Responsibility
    (Elsevier Science Inc, 2015-04-01) Pearce, Craig L.; Stahl, Guenter K.
    The world is at a tipping point. We are simultaneously on the edge of unprecedented wealth creation and catastrophic implosion, as a result of many geopolitical forces. On the one hand, the financial crisis precipitated mainly by events in the United States, and the ripple effects throughout Europe and the rest of the world are slowly coming under control. Yet, at the same time, much of the world is restive. Sub- Saharan Africa, particularly Nigeria, Niger, Cameron and Chad, are in de facto war with extremists intent on returning the region to the Stone Age. The same is true in Syria and the region around it, as we see various groups struggle for complete domination. In Eurasia, Russia has invaded, or threatened to invade multiple of its neighbors (e.g., Estonia, Georgia, Mol-dova, Ukraine). The Taliban is resurging, threatening peace and tranquility in but another beleaguered region.

    Where Do We Go From Here? Is Responsibility Sustainable?
    (Elsevier Science Inc, 2015-04-01) Wegge, Juergen; Pearce, Craig L.
    In this special issue we have brought together a veritable ‘‘dream team’’ of thought leaders, and rising stars, from academia, consulting and the c-suite to address the ‘‘Leadership Imperative for Sustainability and Corporate Social Responsibility.’’ Clearly, the decisions and actions of individual leaders matter to the social performance and long-term viability of their organizations. Ultimately, activities such as formulating sustainability policies, engaging in community outreach programs, supporting social causes, or seeking alternatives to disruptive layoffs are the result of managerial decisions, and so are activities that are widely considered unethical, such as bribery, fraud, environmental pollution, and employment discrimination. While corporate executives are constrained in their ability to engage in these activities by corporate governance regulations, company policies, and the law, they have some degree of discretion in their choices. David Waldman, a noted leadership scholar, put it succinctly:‘‘Firms do not make decisions pertaining to responsibility or CSR; leaders do."
