Market Segmentation of Leisure Boats Exhibited in the Boat Show by Using Multivariate Statistical Techniques

The aim of this study is to segment recreational boats according to their basic parameters in order to develop marketing strategies and to investigate the benefit/cost factors in consumer preferences across segments. For this purpose, 69 recreational boats under 10 meters exhibited at the Istanbul Boat Show were clustered using basic parameters. In the study, in which hierarchical clustering and multidimensional scaling analysis were used, the boats were divided into four clusters and these results were intended to create an input in the marketing strategies of the boats. These clusters are labelled from the lowest segment to the highest segment, A, B, C and D in ascending order. Based on the calculated averages of these segments for five variables, their intended use is introduced. This segmentation provides guiding findings in different areas such as marketing, advertising and production strategies from the arrangement of the boats within the fair. In addition, alternative actions have been determined for both the customer and the seller by revealing the costs to be incurred in the event that customers prefer different segments

Analysing the Financial Ratios of the Companies in the Maritime Industry with Multivariate Statistical Techniques

This study aims to glance at the shipping sector in terms of financial ratios. To this end, 23 financial ratios were collected from each of the 223 companies worldwide and examined by factor analysis. Seven factors were spotted explaining 85% of the total variance. Subsequently, multidimensional scaling was conducted to analyse the sector on these seven factors. The findings demonstrate profitability ratios as the biggest source of variability and as the reason for the differences among companies. The findings also show that the profitability ratios can be used for monitoring, early warning or decision making purposes for the shipping sector

For this, four different sowing times (20 September, 10 October, 30 October and 20 November) were tested and split plots design was used with four replications. According to the results obtained from the research, the effects of sowing date of varieties on yield and yield components were different and significant. The highest grain yield was obtained 450.0 kg/da for Gönen variety in sowing date of 20 November. As a result, the most suitable sowing date of wheat under the ecological conditions of Çanakkale was from 10 October to 20 November. Key Words: Winter wheat, cultivar, sowing date, grain yield, yield components

Relation of gallbladder function and Helicobacter pylori infection to gastric mucosa inflammation in patients with symptomatic cholecystolithiasis

Background. Inflammatory alterations of the gastric mucosa are commonly caused by Helicobacter pylori (Hp) infection in patients with symptomatic gallstone disease. However, the additional pathogenetic role of an impaired gallbladder function leading to an increased alkaline duodenogastric reflux is controversially discussed. Aim:To investigate the relation of gallbladder function and Hp infection to gastric mucosa inflammation in patients with symptomatic gallstones prior to cholecystectomy. Patients: Seventy-three patients with symptomatic gallstones were studied by endoscopy and Hp testing. Methods: Gastritis classification was performed according to the updated Sydney System and gallbladder function was determined by total lipid concentration of gallbladder bile collected during mainly laparoscopic cholecystectomy. Results: Fifteen patients revealed no, 39 patients mild, and 19 moderate to marked gastritis. No significant differences for bile salts, phospholipids, cholesterol, or total lipids in gallbladder bile were found between these three groups of patients. However, while only 1 out of 54 (< 2%) patients with mild or no gastritis was found histologically positive for Hp, this infection could be detected in 14 (74%) out of 19 patients with moderate to marked gastritis. Conclusion: Moderate to marked gastric mucosa inflammation in gallstone patients is mainly caused by Hp infection, whereas gallbladder function is not related to the degree of gastritis. Thus, an increased alkaline duodenogastric reflux in gallstone patients seems to be of limited pathophysiological relevance. Copyright (c) 2006 S. Karger AG, Basel

Effect of Logistics Performance Index on Human Development Index: An Application to Logistics Sector

Human Development Index (HDI) has been subject to a lot of criticism over time, with the idea that it does not fully reflect human development, and has been complemented with different indicators in various studies. Despite its importance, especially considering the requirements of the era, logistics has not been considered with HDI and, although there are many synthetic indices that combine different methods (i.e. DEA, MCDM etc.) with HDI, these indices are far from reaching logical results. Logistics is a fundamental activity in meeting all human needs, and therefore should be considered as a measure of countries\u27 human development. Therefore, this study offers a revision of the HDI with special consideration to the logistics performances of countries. It is observed that infrastructure and timeliness indicators from these sub-indicators of Logistics Performance Index (LPI) have a significant effect on the HDI. Using the United Nations\u27 HDI calculation method with the statistically significant indicators, Logistics-HDI (L-HDI) is developed and proposed as a new index. This study argues that L-HDI reflects the human development of countries more appropriately. The L-HDI will also offer better benchmarking than other synthetic indices in its scientifical field
