Item Open Access The effect of uncertainty on learning in game-like environments(Pergamon Press, 2013) Ozcelik, E.; Cagiltay, N. E.; Ozcelik, N. S.Considering the role of games for educational purposes, there has an increase in interest among educators in applying strategies used in popular games to create more engaging learning environments. Learning is more fun and appealing in digital educational games and, as a result, it may become more effective. However, few research studies have been conducted to establish principles based on empirical research for designing engaging and entertaining games so as to improve learning. One of the essential characteristics of games that has been unexplored in the literature is the concept of uncertainty. This study examines the effect of uncertainty on learning outcomes. In order to better understand this effect on learning, a game-like learning tool was developed to teach a database concept in higher education programs of software engineering. The tool is designed in two versions: one including uncertainty and the other including no uncertainty. The experimental results of this study reveal that uncertainty enhances learning. Uncertainty is found to be positively associated with motivation. As motivation increases, participants tend to spend more time on answering the questions and to have higher accuracy in these questions. © 2013 Elsevier Ltd.

An empirical research revealed that Imager students outperformed Verbalisers in both drafting and creativity scores. Wholist-Analytic cognitive style dimension was found to be independent from drafting and design performance. The study suggests that examining the cognitive styles of students in Computer Aided Design (CAD) education deserves further attention and may facilitate for improvements in learning processes. © 2008 Springer Science+Business Media B.V.Item Open Access Football and exchange rates: empirical support for behavioral economics(Sage Publications, Inc., 2007) Eker, G.; Berument, Hakan; Dogan, B.Recently, economic theory has been expanded to incorporate emotions, which have been assumed to play an important role in financial decisions. The present study illustrates this by showing a connection between the sports performance of popular national football teams (Besiktas, Fenerbahce, and Galatasaray) and performance of the Turkish economy. Specifically, a significant positive association was found between the success of three major professional Turkish football teams and the exchange rate of the Turkish lira against the U.S. dollar. The effect of the football success of several Turkish football teams on the exchange rate of the Turkish lira was examined using the simultaneous multiple regression model with predictor measures of wins, losses, and ties for different combinations of teams to predict the depreciation rate of the Turkish lira between the years 1987 and 2003. Wins by Turkish football teams against foreign (non-Turkish) rivals increased with exchange rate depreciation of the Turkish lira against the U.S. dollar. © Psychological Reports 2007.Item Open Access International Outsourcing: Empirical Evidence from the Netherlands(2011) Tuluǧ Ok, S.This study examines the results of a fi eld survey on international outsourcing conducted in 2009 in the Netherlands. The research sample is composed of 156 Dutch enterprises from various industries. Empirical evidence shows that reduction of labor costs, improved competitiveness, strategic decisions taken by the group head and reduction in other costs are the main motivations for Dutch fi rms to engage in international outsourcing. Tax and regulatory advantages seem to play a lesser role. The motivations can be grouped into three distinct factors: access to cheaper resources and increasing competition, access to scarce and distinctive resources and reduction of other production costs. The most important impediments turn out to be problems with distance to producers, the need for proximity to existing clients, concerns about the outsourcing operation exceeding expected benefi ts and linguistic/cultural barriers. Violation of patents/intellectual property rights and uncertainty of international standards are not viewed as important issues. The impediments are captured by three different dimensions as indicated by the data: legal and governmental obstacles, human concerns and logistical diffi culties. © 2011 Vilnius Gediminas Technical University (VGTU) Press Technika.
