The aim of this study to examine the performance of Support Vector Regression (SVR) which is a novel regression method based on Support Vector Machines (SVM) approach in predicting the Istanbul Stock Exchange (ISE) National 100 Index daily returns. For bechmarking, results given by SVR were compared to those given by classical Linear Regression (LR). Dataset contains 6 technical indicators which were selected as model inputs for 2005-2011 period. Grid search and cross valiadation is used for finding optimal model parameters and evaluating the models. Comparisons were made based on Root Mean Square (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), Theil Inequality Coefficient (TIC) and Mean Mixed Error (MME) metrics. Results indicate that SVR outperforms the LR for all metrics.

Location selection problem in banking is an important issue for the commercial success in competitive environment. There is a strategic fit between the location selection decision and overall performance of a new branch. Providing physical service in requested location as well as alternative distribution channels to meet profitable client needs is the current problematic to achieve the competitive advantage over the rivalry in financial system. In this paper, an integrated model has been developed to support in the decision of branch location selection for a new bank branch. Analytic Hierarchy Process (AHP) technique has been conductedto prioritize of evaluation criteria, and multi-objective optimization on the basis of ratio analysis (MOORA) method has been applied to rank location alternatives of bank branch.

Today, the importance of innovation for enterprises, increase each passing day. As a result of globalization, enterprises are under intense competitive pressure. They have to make innovation for increasing to market share or for protecting to it at least. Non- innovative firms lose their customers and their existence is face to threat from other innovative actors in the market. Therefore firms have to design their organization structure that encourage to innovation. Mintzberg’s adhocratic organization structure was investigated in this article. Thus, its aim of this study leads to resemblance and diversity between theory and practice via of the theoretical knowledge. As a result of study; high degree of similarity between the application and Mintzberg’s theory, which is related to adhocratic organization structure, has been identified.

This article was a result of an investigation measuring the ‘Correlation between Borrower Education and Non-payment Behaviour in Low Income Homeowners in South Africa as the premise of the study and poor relationship between lenders and borrowers as the secondary proposition. The study was motivated by the high level of foreclosures for non-payment of mortgages in the Protea Glen area in Johannesburg, Gauteng, as reported by the Human Rights Commission Inquiry in 2008. In investigating this non- payment behaviour the researcher employed largely quantitative instruments supplemented by qualitative methods. The study revealed interesting empirical findings that largely invalidated the founding hypotheses, despite existing theoretical frameworks - underpinned by various scholars - that sought to corroborate the hypotheses. The findings have however supported the premise that households reporting poor relationships with lenders were susceptible to non-payment behaviour. The rest of the secondary hypotheses were rejected by the empirical findings, viz. that there was no correlation between the level of formal education and non-payment behaviour; the link between propensity to default and the age of homeowners were also invalidated. From these findings, it can be demonstrated that there is a critical need for mitigating measures to remedy the identified shortcomings in this sector.

Owing to aesthetic components that advertisement texts generally have, advertisements are sometimes perceived as a genre of art by some circles. The study is based upon a perspective presented by an interdisciplinary background and it acknowledges a paradigm that advertising is not a genre of art, it obviously pursues commercial profits and within this context, expolits the created aesthetics in product. The main objective of the study, which focuses advertising aesthetic fundamentally, is to build a scientific model formulating some levels of aestheticisation during its production process. Formulation in question has been reconstructed on theoretical and applied literature.
