Abstract. This study combines AHP and GIS to provide decision makers with a model to ensure optimal site location(s) for fire stations selected. The roles of AHP and GIS in determining optimal locations are explained, criteria for site selection are outlined, and case study results for finding the optimal fire station locations in Istanbul, Turkey are included. The city of Istanbul has about 13 million residents and is the largest and most populated city in Turkey. The rapid and constant growth of Istanbul has resulted in the increased number of fire related cases. Fire incidents tend to increase year by year in parallel with city expansion, population and hazardous material facilities. Istanbul has seen a rise in reported fire incidents from 12 769 in 1994 to 30 089 in 2009 according to the interim report of Istanbul Metropolitan Municipality Department of Fire Brigade. The average response time was approximately 7 min 3 s in 2009. The goal of this study is to propose optimal sites for new fire station creation to allow the Fire Brigade in Istanbul to reduce the average response time to 5 min or less. After determining the necessity of suggesting additional fire stations, the following steps are taken into account: six criteria are considered in this analysis. They are: High Population Density (HPD); Proximity to Main Roads (PMR); Distance from Existing Fire Stations (DEF); Distance from Hazardous Material Facilities (DHM); Wooden Building Density (WBD); and Distance from the Areas Subjected to Earthquake Risk (DER). DHM criterion, with the weight of 40%, is the most important criterion in this analysis. The remaining criteria have a weight range from 9% to 16%. Moreover, the following steps are performed: representation of criterion map layers in GIS environment; classification of raster datasets; calculating the result raster map (suitability map for potential fire stations); and offering a model that supports decision makers in selecting fire station sites. The existing 35 fire stations are used and 17 fire stations are newly suggested in the study area.

With the growth of international trade and travel, consumers are increasingly confronted with foreign products and services. But some negative attitudes towards foreign products can arise from several factors such as previous or ongoing political, military, economic, or diplomatic events. Thus, both consumer ethnocentrism and consumer animosity have become important constructs in marketing. The purpose of this study is to investigate whether consumer ethnocentrism and consumer animosity affect repurchase intent towards U.S. products and whether this impact is moderated by customer loyalty. The findings of the research indicate that consumer ethnocentrism increases consumer animosity for the sampling. The present study also denotes that both consumer ethnocentrism and animosity have a negative impact on repurchase intent toward U.S. products in Turkey. According to the results of regression analyses, customer loyalty may not be an important moderating factor between consumers' animosity and repurchase intent toward U.S. products. However, customer loyalty moderated the relationship between consumer ethnocentrism and repurchase intent toward U.S. products. Further implications for Turkish consumers in supermarkets in the province of Nevşehir are discussed. The value of future research is also acknowledged

Objective: The aim of this study is to investigate the role of activated protein C resistance (APCR) as a contributing factor in the pathogenesis of myocardial infarction. Methods: Forty patients with acute myocardial infarction (AMI) who have been followed by the Cardiology Department of Gülhane Military Medical Academy Haydarpaşa Training Hospital and 30 healthy individuals were included in this study. Patient group consisted of 27 males and 13 females, (mean age 47.9 (23-81) control group composed of 16 males and 14 females, (mean age 46.1 (24-63) Whole blood count and routine biochemical work up were performed and activated protein C resistance (APCR) ratio, and activated partial thromboplastin time were evaluated in both groups. Results: Two patients and three controls had APCR. Mean APCR ratio was 2.56 ± 0.56 in the control and 2.74 ± 0.67 in the patient group and there was no statistically significant difference between the two groups (p>0.05). Conclusion: Although APCR is a major risk factor for venous thrombosis, its role in the pathogenesis of AMI is not clearly understood.
