    Financial Innovation-Crowdfunding: Friend or Foe?
    (Elsevier, 2015) Son-Turan, Semen; Turan, Semen Son
    A phenomenon with a considerable past, and with new conspicuous investment models and financial products and servicesproliferated through the Internet; financial innovation seems to be almost ubiquitous these days. While there are numerousadvantages, especially nowadays through the exploitation of easily accessible, low cost and convenient e-commerce platforms,innovation in the finance sector does not come without its perils. Banks and traditional financial institutions are losing chunks ofmarket share to virtual intermediaries and investors are operating in relatively less regulated and, consequently, less secureenvironments. Furthermore, from the perspective of all stakeholders, there is a Knightian uncertainty component of the long-termramifications in investing in and through newly developed products and platforms. As such, it is only recently that economichistory witnessed the outbreak of the sub-prime mortgage crisis caused by the unraveling of a chain of events interlinked throughthe imprudent use of “innovative” derivative transactions involving credit default swaps backed by the insatiable appetite of the“irrationally exuberant” investor and the easement of regulation paving the leeway for predatory lending. This paper investigateswhether and to what extent innovative investment models such as crowdfunding, as the game-changer, forcing the tightlyregulated securities markets to adapt to the rules of the WEB 3.0 era and relieved through the provision, Title III, of the JOBSAct, could be a potential peril. To that end, it discusses the evolution of the equity crowdfunding model in the realm of thetechnology push - demand pull framework and analyzes the current situation of the market.

    Reforming Higher Education Finance in Turkey: the Alumni-Crowdfunded Student Debt Fund "a-Csdf" Model
    (TEDMEM, 2016) Son-Turan, Semen
    This study presents an innovative and sustainable system formobilizing Turkish university alumni to contribute to acrowdfunded pool repackaged as a student debt instrument withan elaborate performance tracking tool, various payoff structuresand income-contingent repayment schedules. The ultimate aim isto offer a remedy for the conspicuous global shortage ofalternative finance sources and various forms of aid to highereducation students in the short-term, and, through enablingequitable and egalitarian access to quality higher education,transforming society and enhancing economic development in thelonger-term. The model rests upon a six-dimensional frameworkand its infrastructure is facilitated by a newly emerged form ofdigitally enhanced financing, “crowdfunding”. The researchmethod involves content analysis and data triangulation forvalidation purposes to determine the sub-themes surrounding thehigher education problem in Turkey. The theme-driven keywordsare searched for on Turkey’s first original social network, EksiSozluk, to uncover trends and biases towards student loans, debtrepayment and associated concepts. Subsequently, the samekeywords are utilized in a Google Trends search volume analysis,and are finally validated by a focus group discussion. Thetheoretical framework to explain students’ attitudes towardsborrowing and loan repayment and the motivation behind alumniand charitable giving, rests mainly on behavioral economics. TheA-CDSF Model uniquely addresses the higher education financeproblem in Turkey and offers an easily implementable originalsolution for institutions and policy makers.

    The Impact of Investor Sentiment on the "leverage Effect"
    (Econometric Research Association, 2016) Son-Turan, Semen
    With the advent of the Internet and the availability of user search query data on a broaderscale, since the early 2000s researchers have started using collective search queryinformation instead of, or, in addition to, traditional investor sentiment proxies. Thisstudy examines whether the leverage (bad news) effect, as measured by theEGARCH (1,1) model, changes with the inclusion of a newly emerging sentiment proxy,internet search volume. The sample consists of 14 US companies belonging to theNASDAQ and NYSE Indices and 501 observations of data collected at weekly frequencyspanning a nine year period. Empirical findings suggest that, inclusion of the investorsentiment variable has no clear impact on the bad news effect; there is, however, adiscernible increase in volatility persistence. The implications of the findings are that theinvestor sentiment proxy has additional informational content. Behavioral finance theoryand the availability and social proof heuristics serve as potential explanations for suchfindings.

    Lean, Green and Clean? Sustainability Reporting in the Logistics Sector
    (MDPI, 2019) Lambrechts, Wim; Semeijn, Janjaap; Son-Turan, Semen; Reis, Lucinda
    Transport 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.

    Coprorate Sustainability Reporting: an Evaluation of Turkish Company Reports
    (MEF Üniversitesi Sosyal Bilimler Enstitüsü, 2021) İyigör, Engin; Semen Son Turan
    The effects of globalization are witnessed clearly in organizations. Interaction areas and stakeholders of organizations, which are living organisms, have moved and differentiated with globalization. This differentiation brought not only profitability but also being sustainable, added value to the society in social and economic terms. Today, it is expected that the activities of organizations are carried out within the framework of corporate social responsibility and governance principles in ecological, environmental and social terms, and the results will be presented to their stakeholders by observing the principles of transparency, accountability and openness. These expectations are met with corporate sustainability reports. This study concentrates on the corporate sustainability reports of Turkey's 500 largest (by sales) companies according to the three companies in the top five in the rankings; Türkiye Petrol Rafineleri A.Ş. (TÜPRAŞ), Türk Hava Yolları A.Ş. (THY) and OPET Petrolcülük A.Ş. (OPET)’s corporate sustainability reports were evaluated comparatively.

    Prediction of Loan Decisions With Optical Neuroimaging (fnirs) and Machine Learning
    (IEEE, 2023) Girişken, Yener; Son Turan, Semen; Çakar, Tuna; Ertuğrul, Seyit; Sayar, Alperen; Son, Semen; Giriken, Yener
    The successful applications of neuroscientific methods and artificial learning approaches have increased in applied fields such as economics, marketing, and finance in the last decade. In this study, a prediction model was developed using the output of optical neuroimaging (fNIRS) measurements from the prefrontal brain regions while 40 participants made decisions for 35 credit offers. The aim was to predict participants' responses to credit offers using artificial learning methods based on four metrics obtained over time from the optical neuroimaging system. The findings of the study indicate that the first 6 seconds (prior to the response entry) are particularly critical. While the performance rate in the developed prediction models is found to be higher, especially in tree-based algorithms, this paper includes a performance comparison of 5 models specifically.

    Improved Business Model Representation of Innovation Concepts
    (World Conference on Technology, Innovation and Entrepreneurship, 2015) Dorantes-Gonzalez, Dante Jorge; Küçükaydın, Hande; Özlem, Şirin; Bulgan, Gökçe; Aydın, Utkun; Son Turan, Semen; Karamollaoğlu, Nazlı; Teixeira, Frederico Fialho
    Except for academics and consultants, the concept and purpose of innovation (not to mention related concepts such as “Open Innovation", "Free-Intellectual Property Innovation," or "Open Source Innovation") is usually unclear for most entrepreneurs and other practitioners. It often times happens that newly coined terminology becomes misleading or may even include a certain degree of sensationalism, hence turning into a matter of debate for specialists in the realm of technology management. Such has been the case for the term “Open Innovation”, since the word “open” is mainly related to crowd sourced innovation, but not for the openness on intellectual property rights. Since innovation is about the commercialization of original ideas, so we propose a simple and visual business model setting to resolve these concepts. To this regard, the “Business Model Canvas” has been used in business and entrepreneurship to sketch and frame the key points behind the development of a startup. This model was suggested by Alexander Osterwalder (2008) in his work on Business Model Ontology, as a strategic analysis template for developing startups or documenting existing businesses. It describes the firm’s value proposition, partners, resources, activities, customer relationships, distribution channels, customers, revenue streams and cost structure. However, when it comes to innovative startups, this template does not explicitly include such significant innovation components as intellectual property, its alignment to strategies, and intellectual property flow. The present paper proposes the use of an improved version of the Business Model Canvas to originally represent different models of innovation like Open Innovation, thus providing a clear, visual and quick representation of their meaning, and consequently, contribute to a better understanding of different concepts of innovation.

    Sustainability Disclosure in Higher Education: a Comparative Analysis of Reports and Websites of Public and Private Universities in Turkey
    (Emerald Group Publishing Ltd., 2019) Son Turan, Semen; Lambrechts, Wim; Son-Turan, Semen
    Purpose : The purpose of this paper is to explain the extent and content of the sustainability disclosure of public and foundation (private but not-for-profit) universities in Turkey. Design/methodology/approach : Subsequent to a systematic literature review of six academic databases and the National Thesis Center, a content analysis using a combination of Global Reporting Initiative and campus assessment tools from previous studies is conducted on stand-alone sustainability reports and websites of a purposive sample of eight universities in Turkey. Findings : Infrequent and unsystematic sustainability practice done through websites seems to be more prevalent than formal reporting through international initiatives. Research and practice diverge by focusing on different sustainability indicators. Sustainability needs to be integrated into teaching and curriculum through university policies and regulations. Foundation universities show greater effort in sustainability reporting than public universities. Research limitations/implications : The research is limited by the availability of mostly self-reported, dispersed and unaudited data by foundation universities in addition to framework-imposed specificities. Furthermore, there is only one public university with a formal sustainability report in the sample.Practical implications : The findings offer suggestions for developing extra sustainability indicators and may assist local policy-makers and researchers in their efforts to improve sustainability reporting by local universities.Originality/value : This comprehensive research effort is one of the few studies from a non-Western country perspective and the only study on Turkey in relation to universities and sustainability reporting. Keywords : Citation Son-Turan, S. and Lambrechts, W. (2019), "Sustainability disclosure
