This research project focuses on the question： Which effects do teachers＇ attitudes have on students＇ academic self-concept and students＇ competences？ The study is informed by the theoretical perspective that competences and individual skills can be improved especially when students and teachers are confident about the possibility of change of these variables and when teachers make this explicit as a central theme. In our intervention study, we investigate whether a change in the teaching and learning setting （moving from a focus on deficits to a focus on strengths） is able to enhance students＇ academic self-concept and students＇ competences, even across domains.     

A dynamic decision model for portfolio investment and assets management

This paper addresses a dynamic portfolio investment problem. It discusses how we can dynamically choose candidate assets, achieve the possible maximum revenue and reduce the risk to the minimum level. The paper generalizes Markowitz＇s portfolio selection theory and Sharpe＇s rule for investment decision. An analytical solution is presented to show how an institutional or individual investor can combine Markowitz＇s portfolio selection theory, generalized Sharpe＇s rule and Value-at-Risk （VaR） to find candidate assets and optimal level of position sizes for investment （dis-investment）. The result shows that the generalized Markowitz＇s portfolio selection theory and generalized Sharpe＇s rule improve decision making for investment.

Model for cascading failures in congested Internet

Cascading failures often occur in congested networks such as the Internet. A cascading failure can be described as a three-phase process： generation, diffusion, and dissipation of the congestion. In this account, we present a function that represents the extent of congestion on a given node. This approach is different from existing fimctions based on betweenness centrality. By introducing the concept of ＇delay time＇, we designate an intergradation between permanent removal and nonremoval. We also construct an evaluation fimction of network efficiency, based on congestion, which measures the damage caused by cascading failures. Finally, we investigate the effects of network structure and size, delay time, processing ability and packet generation speed on congestion propagation. Also, we uncover the relationship between the cascade dynamics and some properties of the network such as structure and size.

The Effect of Culture Integrated Language Courses on Foreign Language Education

When examined carefully, it is seen that there is not an available and detailed cttrriculum designed for the aim of foreign language teaching with integrated cultural items of the target language in the programs of the schools under authority of the Ministry of Education and Turkish higher education institutions. In recent years, the specialists have an agreement on the issue that foreign language instruction should be carried out by the means of target language＇s history, literature, geography and also its social characteristics. The idiom ＂it＇s raining cats and dogs＂ can be misinterpreted by a Turkish student without the knowledge of this idiom＇s story in English history as ＂Cats and dogs are pouring down from the sky＂. An important French architectural building ＂Saint Mary Cathedral, Notre Dame de Paris＂ can be misunderstood as ＂Our Parisian Woman＂ by a student who is unfamiliar with French culture. Both examples show that encountered foreign words and phrases can be misunderstood and mostly these words are perceived and interpreted according to learners＇ own cultural figures. The aims of this study are to show the significance of culture-based foreign language courses and to make a contribution to the literature by regarding the views of researchers beheving that culture and language are inseparable concepts. In this context, Erzincan University French Language Teaching Department students＇ opinions on the relation between culture and language learning were received with the application of qualitative structured written response method. Then, document analysis of written comments was evaluated. Consequently, the analysis on the participants＇ written comments showed that a culture integrated foreign language course can make positive contributions to students＇ learning, language learning process and learning environment.

Research on Information Hiding

With the development of information technology, people have paid more and more attention on the information security today. Information hiding research has become the focus of the information security research. Because every Web sites and network communication depend on the multimedia, such as audio, video, image and so on. Information hiding technology can embed secret information into a digital media source without impairing the perceptual quality of that source. Other people can＇t feel this secret information.

E-learning and Evaluation in Modern Educational System

Implementation of information and communication technologies as well as emersion of new user interfaces and web 2.0 technologies changes the way of education system, the way of living and business transactions in general. The way we communicate, operate, produce and live is also changing. In accordance with it, the systems of education change from traditional to modern. The following changes occur： from content delivery to knowledge production, from transfer of knowledge from teachers to students towards encouragement of development and construction of knowledge, from courses and programs changing to the adaptation of the study environment, from the faculty professionalism to the quality of teaching and student learning and the early involvement of students in research work and projects. These occurring changes also affect the students＇ and professors＇ mobility. Here, the word ＂mobility＂ represents not only the student exchange programs and the easier transitions from one＇s home university to a foreign one, but also the way professors conduct their classes. With the development of certain software, students＇ class attendance no longer represents an important factor, as they can now learn from distance using the mentioned software, taking the learning process one step further. In order for above-mentioned changes to occur, the use of e-learning and the development of new tools are almost mandatory. With this in mind, the goal of this paper is to analyze quantitatively the changes that are occurring almost every day that affect the students＇ learning and the professors＇ teaching methods.
