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: 94Blockchain 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: 20Citation - Scopus: 23Voluntary 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.Article Citation - WoS: 10Citation - Scopus: 10Introduction 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.Article Citation - WoS: 3Citation - Scopus: 8Where 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."Article Citation - WoS: 21Citation - Scopus: 21Testing for Systemic Risk Using Stock Returns(Springer, 2016-05-26) Kupiec, Paul; Güntay, LeventThe literature proposes several stock return-based measures of systemic risk but does not include a classical hypothesis tests for detecting systemic risk. Using a joint null hypothesis of Gaussian returns and the absence of systemic risk, we develop a hypothesis test statistic to detect systemic risk in stock returns data. We apply our tests on conditional value-at-risk (CoVaR) and marginal expected shortfall (MES) estimates of the 50 largest US financial institutions using daily stock return data between 2006 and 2007. The CoVaR test identifies only one institution as systemically important while the MES test identifies 27 firms including some of the financial institutions that experienced distress in the past financial crisis. We perform a simulation analysis to assess the reliability of our proposed test statistics and find that our hypothesis tests have weak power, especially tests using CoVaR. We trace the power issue to the inherent variability of the nonparametric CoVaR and MES estimators that have been proposed in the literature. These estimators have large standard errors that increase as the tail dependence in stock returns strengthens.Article Citation - WoS: 33Citation - Scopus: 44Lean, Green and Clean? Sustainability Reporting in the Logistics Sector(MDPI, 2019-01-09) Lambrechts, Wim; Semeijn, Janjaap; Son-Turan, Semen; Reis, LucindaTransport and logistics activities contribute heavily to global sustainability problems, yet the implementation of corporate social responsibility and sustainability reporting in the sector lags behind. This paper aims to analyze sustainability reporting in the logistics sector, with focus on environmental, social and economic indicators. An extensive operationalization of sustainability indicators is used to examine and analyze the sustainability reports of 52 organizations in the logistics sector worldwide. Results show that the sector does not agree on the materiality of sustainability indicators. Furthermore, sustainability reporting seems to be incompatible with daily operations, leading to obscurity in reports. This contrast, between the necessary existence of organizations in the logistics sector and their undesirable environmental and social effects, calls for future research into how organizations are coping with this paradox. A viable way forward is needed in order to ensure materiality in the sectors’ efforts toward sustainability reporting.Article Citation - WoS: 29Citation - Scopus: 41The Impact of Industry, Firm Age and Education Level on Financial Management Performance in Small and Medium-Sized Enterprises (smes): Evidence From Turkey(Emerald Publishing, 2017-09-04) Karadağ, HandeSmall and medium sized enterprises are crucial for socio-economic growth, due totheir significant role in creating new workforce, GDP increase, innovation andentrepreneurship. This article examines financial management performance in smalland medium-sized enterprises with regard to industry, firm age and education level ofowner/managers differences. The data used in the study is collected from 188 smalland medium-sized enterprises through structured questionnaires and threehypotheses regarding the associations are tested by using structural equationmodeling. Findings of one-way ANOVA tests indicate that performance in financialmanagement practices has a strong and positive correlation with education level ofsmall business owner/managers, whereas no significant difference is found regardingSMEs operating in different industries. For the impact of company age, independentsamples T-test is conducted and a meaningful difference between small andmedium sized companies which are five years or older and younger is found.
