Article An Empirical Study of Sequential Offer Bargaining During the Festival of Sacrifice(Elsevier, 2024) Dindaroğlu, Burak; Ertaç, SedaWe report results from a unique data set of real -life bargaining transactions collected from the market for livestock (sheep) before the Festival of Sacrifice (Eid al-Adha) in Izmir, Turkey. This market is characterized by frequent and aggressive bargaining, which occurs in the form of sequential price offers. We record bargaining transactions as they occur, and collect detailed information on the bargaining environment, as well as on the characteristics of buyers and sellers. We also elicit each seller's outside option by means of an incentive compatible mechanism and obtain a reported maximum willingness to pay from buyers. We particularly focus on aspects of the bargaining process, such as non -price communication. In different types of empirical analysis, results robustly indicate that the presence and content of communication matters, for the likelihood of a sale as well as concessions made. Specifically, buyer -side communication is associated with larger concessions from the seller and a higher probability of sale. The presence of a mediator during the negotiation is associated with a higher probability of sale as well, while it has no effect on prices. We also provide results on the relative importance of groups of variables for predicting bargaining outcomes, which can provide directions for further research in bargaining.Article Citation - WoS: 4Citation - Scopus: 2Unwanted Others of the City: Counter-Cultural Production of the Roma People of Urla-Turkey(Taylor & Francis, 2024) Uştuk, OzanThis article examines a case of urban displacement and its impact on the local Roma community by uncovering the discursive strategies of the local governments and the tactical responses of the local people. Based on two-year-long ethnographic research, this study aims to understand the intricate dynamics of the counter-cultural production of the Roma people as a response to gentrification policies of local governments. The rapid rise of the rent value of land has motivated the capital class to force an exile strategy on Roma and accelerated existing segregation policies. During this time, some discursive strategies to manufacture public consent about the gentrification have circulated to change the representation of the Roma identity, replacing their imagery in mainstream society by mainly signifying them as the undeserving poor. This research aims to understand how strategic discourses and actions have positioned Roma in the societal and cultural sphere and in response, how everyday tactics of the Roma engenders counter-cultural forms through intercultural communication.Article Citation - WoS: 1Network Analysis of Innovation Mentor Community of Practice(Emerald Group Publishing, 2023) Altınışık, Günda Esra; Aydın, Mehmet Nafiz; Perdahçı, Ziya Nazım; Pasin, MerihPurposePositive effect of knowledge sharing (KS) on innovation has come to the fore and government-supported innovation and mentoring communities or mentor networks have become widespread. This article aims to examine the community connectedness and mentors' preferences for professional competency-based KS of such innovation community of practice networks (CoPNs).Design/methodology/approachThe paper constructs a directed weighted CoPN model with a node-attribute-based novel fingerprint edge weights. Based on the CoPN, Social Network Analysis (SNA) metrics and measures including Giant Component (GC) were proposed and analyzed to identify mentors' connectedness preferences. The fingerprint was proposed as a novel binarized node attribute of competence. Jaccard similarity of fingerprints was proposed as edge weights to reveal correlations between competences and preferences for KS.FindingsThe work opted to conduct a survey of 28 innovation mentors to measure a CoPN. Both a name generator question and a second set of questions were employed to invite respondents to name their collaborators and indicate their professional competence. SNA metrics result in differing values for GC and the rest, which lead us to focus on GC to reveal salient metrics of connectedness. Jaccard similarity analysis results on GC demonstrate that mentors collaborate in an interdisciplinary manner.Originality/valueBased on the CoPN, the methods proposed may be effective in predicting preferred relationships for interdisciplinary collaborations, providing the managers with an analytical decision support tool for KS in practice.Article Interpersonal Trust, Invention, and Innovation Across European Regions(John Wiley and Sons Inc, 2023) Dindaroğlu, BurakMany studies in economics and regional science claim a positive link between interpersonal trust and innovation by demonstrating a positive effect of trust on patenting. This contrasts many findings from organization level studies on trust and innovation, who report a variety of findings including inverted-U type relations. A possible explanation is that trust exhibits different roles in invention and innovation, as the former relies on knowledge commons while the latter directly embeds commercialization and the market context. This study attempts to reconcile the two set of findings by studying indicators of invention and innovation in relation to trust at the same unit of observation, by using the regional variation in Europe. I study the relationship between interpersonal trust and patent applications (a measure of invention), trademark applications (a composite indicator) and the share of innovative sales in turnover by SMEs (a direct indicator of commercialization), across European regions. I show that trust positively affects trademark applications with an effect that is comparable to that on patent applications. However, trust exhibits an inverted-U type relationship with innovative sales. Results collectively point to a strong role of trust in all three creative activities, including a negative effect at the higher end when the indicator is directly contingent on commercialization and sales. I also estimate the extent of spatial spillovers in the effect of trust on all three creative outcomes. © 2023 Wiley Periodicals LLC.Article Gezegensel Siyaset Manifestosunun ardından yeşil teorinin uluslararası ilişkilerdeki konumu(Uluslararası İlişkiler Konseyi Derneği, 2022) Buhari Gülmez, Didem; Aydın Dikmen, BengüThis article sheds light on the current debates on the Planetary Politics Manifesto in order to better locate Green Theory in International Relations. In particular, it aims to go beyond the problem-solving vs critical theories binary that is observed in the studies on the location of Green Theory in the discipline. Therefore, rather than comparing Green Theory with the mainstream theories of International Relations, it focuses on the complex relationship between Green Theory and major critical theories such as Constructivism, Normative Theory, Poststructuralism, Critical Theory, Postcolonialism and Feminism from the perspective of the Planetary Politics Manifesto.Article Citation - WoS: 5Citation - Scopus: 5A Novel Risk Analysis Approach for Occupational Safety Using Bayesian Network and Interval Type-2 Fuzzy Sets: the Case of Underground Mining(IOS Press BV, 2022) Yaşlı, Fatma; Bolat, BersamOccupational safety problems are no longer acceptable for any industrial environment. Lack of comprehensive and reliable evaluations for occupational safety causes many undesired events and harm to employees during the industrial process. In this study, it is aimed to develop an applicable risk analysis methodology for evaluating the undesired occupational events that occurred in the multi-process system where no historical accident records. The difficulty in obtaining and analyzing the data required for the determination of the occupational safety risks especially in the manually executed processes has been overcome with the Bayesian Network and interval type-2 fuzzy sets by using the expert judgments. While BN enables to development of a comprehensive reasoning approach about the occurrence of the events, interval type-2 fuzzy sets better represent the ambiguity in the judgments by covering the uncertainty in a wider mathematical range with less computational effort according to other fuzzy sets. During multi-processes in industrial activity, various occupational undesired events may occur, including rare events with very serious consequences or frequent events with very low severity consequences. To able to consider all kinds of events occurring in an industrial environment from a holistic risk perspective, a novel fuzzy scale for specifying the probability and consequence of the events are proposed by the interval type-2 fuzzy numbers. Therefore, all undesired events regardless the probability and consequence which may occur during the multi-processes in a system and the main root causes of these events can be observed within the proposed methodology. A case study is used to emphasize the effect of the proposed methodology for risk analysis of occupational safety in underground mining The results have indicated that occupational safety education is the most contributing factor to occurring the undesired occupational events in underground mining We believe that this study could help evaluate the safety risk of the multi-process systems comprehensively and holistically and proposing strategic planning for mitigating the occupational safety risks.Article Citation - WoS: 3Fragmentation of J/Psi in jets in pp collisions at root S=5.02 TeV batoul diab for the CMS collaboration(Elsevier Ltd., 2019) Karapınar, Güler; CMS CollaborationThe fragmentation of jets containing a J/psi meson is studied in root s = 5.02 TeV pp data using an integrated luminosity of L = 27.39 pb(-1). The fraction of the jet transverse momentum p(Tjet) carried by the J/psi is measured for prompt J/psi and J/psi coming from b hadron decays, named nonprompt. Whereas the fragmentation function of nonprompt J/psi is well-modeled by simulations using a Monte Carlo generator, the prompt J/psi are found to be accompanied by a larger level of jet activity. The fraction of J/psi mesons that are produced inside a jet is also reported, and found to be larger in data than in simulation, for both prompt and nonprompt J/psi.Article Multiparticle Correlations and Higher Order Harmonics in Ppb Collisions at Root S(nn)=8.16 Tev(Elsevier Ltd., 2019) Karapınar, Güler; CMS CollaborationThe elliptic and higher-order azimuthal anisotropy Fourier harmonics (v(n)) are obtained for pPb collisions at root s(NN) = 8.16 TeV over a wide range of event multiplicities based on multiparticle correlations. The data were collected by the CMS experiment during the 2016 LHC run. A sample of peripheral PbPb collisions at root s(NN) = 5.02 TeV covering a similar range of event multiplicities to the pPb results is also analyzed for comparison. The ratios of different harmonic moments are obtained for both v(2) and v(3) with high precision, which allows a direct comparison to theoretical predictions assuming a hydrodynamic evolution of the created medium with initial-state density fluctuations, particularly probing the non-Gaussian nature of initial-state fluctuations in small collision systems. The presented results provide crucial insights into the origin of collective long-range correlations observed in small collision systems.
