Article Citation - WoS: 6Citation - Scopus: 6Excessive Damage Increase in Dual Phase Steels Under High Strain Rates and Temperatures(Sage Publications Ltd, 2021) Cobanoglu, Merve; Ertan, Rasim K.; Simsir, Caner; Efe, MertDamage formation in dual phase steels is a complex process and it may be sensitive to the deformation conditions and mechanisms. In this study, the damage parameter is measured and compared under quasi-static and industrial forming conditions (temperatures: 25 vs 200, 300 degrees C and strain rates: 10(-3)vs 10 s(-1)) for DP590 and DP800 steels. Resonance frequency and ultrasonic sound velocity techniques are utilized for the measurements to test the effectiveness and validity of each technique. At a given strain, the damage values can be up to 700% higher at industrial forming conditions, under which dynamic strain aging (DSA) controls the deformation behavior. DSA results in lower formability and is the likely mechanism responsible from the abnormal damage evolution. Measured damage parameters are also confirmed with the void fraction characterization by microscopy, which also provided details on the void shape and distribution with respect to the deformation conditions.Article Citation - WoS: 76Citation - Scopus: 109Effect of Social Media Sharing on Destination Brand Awareness and Destination Quality(Sage Publications Ltd, 2020) Dedeoglu, Bekir Bora; van Niekerk, Mathilda; Kucukergin, Kemal Gurkan; De Martino, Marcella; Okumus, FevziThis study examines the effect of social media sharing on tourism destination brand awareness and destination natural and service quality and also examines the moderating roles of country of origin (COI; macro and micro) image on destination natural and service quality. Data were collected from 568 domestic and international tourists who have visited Alanya, Turkey. Relationships in the study were examined through structural equation modeling. As one of the components of social media sharing, participant sharing positively affects destination brand awareness, whereas any significant effect of nonparticipant sharing on destination brand awareness was not found. Destination brand awareness positively influences tourist perceptions of both destination service quality and destination natural quality. COI image moderates most of the relationships.Article Citation - WoS: 22Citation - Scopus: 24The Role of Covid-19 Anxiety and Social Contact Within Technology Readiness and Acceptance Model for Virtual Reality(Sage Publications Ltd, 2023) Ozekici, Yakup Kemal; Kucukergin, Kemal GurkanThis research aims to question the current threats posed by COVID-19 anxiety and the concept of social contact brought up by the pandemic, with the goal of extending the TRAM model within the context of tourism and virtual reality (VR). The sample of the study comprises of 300 participants taking part in a touristic activity within the last year and experiencing the lockdown period. Partial Least Squares Structural Equation Modeling (PLS-SEM) is used for data analysis. According to the findings, COVID-19 anxiety significantly enhances attitudes toward VR, social contact as a tourist role, and perceived usefulness (PU) toward VR. However, social contact is shown not to have a significant effect on attitudes toward VR. Lastly, technological readiness predicts perceived ease of use (PEOU) and PU of VR. The two, in turn, affect attitudes toward virtual reality technology (AVR), which positively affects behavioral intention toward virtual reality technology, namely, BIVR. Insights derived from the study extend present knowledge concerning TRAM, COVID-19 anxiety, virtual reality, social contact as a value, and provide various recovery marketing-oriented strategies for tourism professionals.
