Abstract: Due to the rapid increase in global competition among organizations and companies, rational approaches in decision making have become indispensable for organizations in today’s world. Establishing a safe and robust path through uncertainties and risks depends on the decision units’ ability of using scientific methods as well as technology. Demand forecasting is known to be one of the most critical problems in organizations. A company which supports its demand forecasting mechanism with scientific methodologies could increase its productivity and efficiency in all other functions. New methods, such as fuzzy logic and artificial neural networks are frequently being used as a decision-making mechanism in organizations and companies recently. In this study, it is aimed to solve a critical demand forecasting problem with ANFIS. In the first phase of the study, the factors which impact demand forecasting are determined, and then a database of the model is established using these factors. It has been shown that ANFIS could be used for demand forecasting.

Abstract: The concept of freedom constitutes the relationship between ethics and politics in Hegel’s thought. Contrary to Kantian understanding of the concept of freedom in which the concept is autonomous from nature and society, Hegel attempts to reconcile the social and individual existence of human being. The first condition of freedom for individual is to have a self-consciousness, that is being aware of himself. But freedom that could not being comprimized with being social is not the real freedom. Hegel also examines freedom in its historal manner. Freedom, in its historical manner, has reached its completed meaning only in Western societies. Hegel thinks that freedom becomes concrete in practical and political manner in Prussian State, in other words, in modern state. According to Hegel the modern state is a state in which justice and power is united. That is, the state has a both political and ethical existence. Hegel suggests that social institutions are legitimized only by realization of freedom. State is also the supreme normative insitution which concretize ethical life. The aim of this study is to understand Hegel’s attempt of synthesizing individual and society by using ethical and political concepts.

Abstract: This study tries to quantify the economic effects of Economic Partnership Agreements (EPAs) which have been negotiating between sub-Saharan Africa (SSA) and European Union (EU). The study addresses the following questions: How are African countries likely to gain or lose from a bilateral trade liberalisation between Africa and the EU?, what are the welfare implications for the African countries from the EPAs?, how will the formation of EPAs affect trade expansion through trade creation and trade diversion effects?, what are the potential fiscal implications of the EPAs. Even though the full reciprocity principle appears to be trade expanding (singularly infavour of EU), this study indicates that it will pose serious implications for deepening of regional integration in Africa because of trade diversion effect between African countries. Another key finding is welfare effect through the way of trade expantion between EU and SSA.
