This course will follow three main paths: Firstly it will introduce philosophy to doctoral students. The meaning of philosophy, its scope, its sub-branches and its different schools will be the subject topic of the first weeks. Then the course will focus on the relation of philosophy with the sources of knowledge and different sciences. Here, Rationalism, Empiricism and Intuitionism will be covered during the following weeks. In the remaining weeks the course will concentrate on philosophy of science and scientific ethics. Logical positivism, paradigm changes, falsificationism, the questions of “what is science”, “what is pseudo-science?”, “what is the relation between theory and reality?” are amongst topics that will be covered. Finally, the course will concentrate on ethical theories and will particularly cover scientific ethics.

This course addresses the emergence of internet technology from a cultural perspective, placing this new medium in a historical context and examining its relationships to older media forms. Students will also consider some of the political, social and economic debates which relate to the production and consumption of internet culture, including surveillance and privacy, the ‘digital divide’, the ‘disruption’ of traditional industries, questions of the psychological impact of internet use, and the capacity of the internet to effect political change. Finally, the course will consider whether the existing theoretical models which scholars use to analyse media and culture are suited to internet technology, or whether new approaches are required.

Nowadays, there exists different alternatives for software development methods and tools to design an information system. The aim of this course is to provide students with the knowledge of the languages ​​that can be used for developing applications for desktop, web and mobile platforms. Besides, alternative databases that can be used for large architectures like relational, distributed and NoSQL databases will be discussed.

This course aims to furnish the students with the tools to analyze, evaluate and improve thinking skills. The most significant variable in determining success or failure is the quality of thinking and it is an indispensable trait for any advance academic study. Based on this perspective students will be encouraged to examine their thinking patterns and put it to some stern tests. After covering standards of thinking and advance thinking techniques, attention will be focused on managerial judgment and leadership wisdom. Managerial judgment and decision making based on wise leadership gained paramount importance in the ever changing and extremely complex environment of our times.

Focusing primarily on the internet and digital cultures, this course will explore the theoretical and practical debates that have developed around the concept of ‘new media’. Topics to be studied include interactivity, social networking, media convergence, cyberculture and the emergence of ‘web 2.0’. Are these developments anticipated by pre-existing studies of communication practice, or are new theoretical models required to understand them?

This course aimed to analyse the forming and designing the planned message and its communication techniques and media within the framework of practices in strategic communication management. Relating to this, the case studies on how the effective media management should be are examined.
