  • Celebrity Endorsement: Developing a Brand Image in Celebrityhousing Ads Endorsement: Developing a Brand Image in Housing Ads
    DOI: 10.5772/intechopen.69651 Provisional chapter Chapter 10 Celebrity Endorsement: Developing A Brand Image in CelebrityHousing Ads Endorsement: Developing A Brand Image in Housing Ads Füsun Çizmeci Yöreş Füsun Çizmeci Yöreş Additional information is available at the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.69651 Abstract This article aims to analyze the celebrity endorsement strategy used to communicate brand image messages in housing advertisements. Even though there is a lot of liter- ature about celebrity endorsement, no research has been made up to now about how this method is used in the housing market. Within the scope of the study, first housing advertisements published from 2001 to 2016 have been scanned. Hurriyet newspaper was selected as the source as it is the newspaper with the highest circulation. After all the advertisements published on Hurriyet newspaper have been scanned, advertisement where a celebrity was the spokesperson was determined. This research, which tries to explain celebrity endorsement widely used for marketing of housings with the “mean- ing transfer model” of McCracken, showed that in transferring cultural meaning of the celebrity to the product or housing, traits of attractiveness or credibility is exploited in general. However, it was seen that other meanings of the celebrity—modern, traditional, etc.—along with his/her credibility and attractiveness are effective in determining the image of the housing project marketed. Keywords: housing adds, brand image, celebrity endorsement, meaning transfer model 1. Introduction Many products or services launched for sale in today’s market conditions are similar to one another in terms of their functional properties and thus it becomes harder to determine the properties that set a brand apart from the others.

  • Interseismic Locking of the Main Marmara Fault in Northwestern Turkey
    Geophysical Research Abstracts Vol. 21, EGU2019-7257-1, 2019 EGU General Assembly 2019 © Author(s) 2019. CC Attribution 4.0 license. Interseismic Locking of the Main Marmara Fault in Northwestern Turkey Zeynep Yılmaz (1), Ali Özgün Konca (2), Semih Ergintav (3), and Robert Reilinger (4) (1) Bogaziçi˘ University, Kandilli Observatory and Earthquake Research Institute, Geophysics Department, Istanbul, Turkey ([email protected]), (2) Bogaziçi˘ University, Kandilli Observatory and Earthquake Research Institute, Geophysics Department, Istanbul, Turkey, (3) Bogaziçi˘ University, Kandilli Observatory and Earthquake Research Institute, Geodesy Department, Istanbul, Turkey, (4) Massachusetts Institute of Technology, Department of Earth, Atmospheric, and Planetary Sciences, Cambridge, Massachusetts, USA Throughout the last century, the North Anatolian Fault (NAF) produced mostly west migrating sequence of M>7 earthquakes, and in this period of time, the NAF did not break beneath the Marmara Sea. The Main Marmara Fault (MMF), which is the north branch of the North Anatolian Fault in the Marmara Region, is the most active branch in this area. The interseismic behavior of the MMF beneath the Marmara Sea is crucial with regards to assessments for the earthquake risk of the Marmara Region which has a population over 24 million. As a result, the prediction of the locking depth and the fault slip rate have great importance as they provide a comprehension concerning the seismic moment deficit, that can be released at the time of a future event. In this study, we modeled the interseismic locking of the MMF by making use of the interseismic GPS ve- locities and implementing a 3D finite-element analysis.

  • Time Frame for Future Large Earthquakes Near İstanbul Based on East-To-West Decelerating Failure of the North Anatolian Fault
    BULUT and DOĞRU / Turkish J Earth Sci Turkish Journal of Earth Sciences Turkish J Earth Sci (2021) 30: 204-214 http://journals.tubitak.gov.tr/earth/ © TÜBİTAK Research Article doi:10.3906/yer-2006-7 Time frame for future large earthquakes near İstanbul based on east-to-west decelerating failure of the North Anatolian Fault Fatih BULUT* , Aslı DOĞRU Geodesy Department, Kandilli Observatory and Earthquake Research Institute, Boğazici University, İstanbul, Turkey Received: 10.06.2020 Accepted/Published Online: 06.11.2020 Final Version: 22.03.2021 Abstract: Large earthquakes that have occurred along the North Anatolian Fault (NAF) were analysed to elaborate the time frame of future large earthquakes near İstanbul. The historical earthquake catalog that was compiled covered 1 nearly complete and 2 fully complete failures of the NAF between 1250 and 2000 AD. These data were used to investigate the space-time systematics of M ≥ 7.0 earthquakes. The catalogue identified an east-to-west decelerating domino-like failure of the NAF. The deceleration starts around the western tip of the 1944 Gerede rupture. This suggested that failure of the remaining unruptured ~250-km section in the west (İstanbul to Saros) will take substantially longer than failure of the already ruptured ~950-km section in the east (Karlıova to İzmit). The calculations indicated that complete failure of the NAF will last for 243 ± 3 years. The deceleration could not be explained by strain partitioning between the subparallel strands of the NAF in the Marmara region. Key words: Future earthquakes near İstanbul, North Anatolian Fault, historical earthquakes 1. Introduction last 2 complete, and partly during the current, incomplete The forecasting of future large earthquakes is significantly failures, and suggested a stochastic relation between the relevant for human life in seismically active regions.
