Item Return and Volatility Connectedness in Electronic Warehouse Receipt Market of Turkey(2023) Acikgoz, Turker; 0000-0002-5613-1929; IYJ-0960-2023Over the course of the last century, globalization and integration have increased significantly around the world. The rise in economic and financial globalization and integration has increased the connectedness between national economies and financial markets and secured an important place in the systemic risk spillover. It is important to analyze the issue in terms of different markets. Food prices around the world have increased significantly over the last 20 years. The price and volatility increase associated with food products lead to important socioeconomic and social problems. In this context, it will be important for decision-makers to assess the issue from the perspective of financial markets and to understand and reveal the dynamic structure of food commodity markets. This study aims to examine the connectedness of return and volatility in the Electronic Warehouse Receipt (EWR) market, where agricultural commodities are traded in Turkey, and to analyze its dynamic structure that changes over time. In this study, the Diebold-Yilmaz connectedness measurement method based on the forecast error variance decomposition after the VAR (p) model was used to analyze the connectedness between financial assets. According to the results of the static analysis performed, it was observed that while the return connectedness in the EWR market is very low, the volatility connectedness is at a higher level than the return connectedness. Based on the results of the dynamic analysis, no trend was observed in return connectedness; however, rapid increases and decreases were observed for certain periods. On the other hand, while an increasing trend was observed in the dynamic analysis of volatility connectedness, sudden increases and decreases were observed during periods of crisis. Of all agricultural commodities, it was observed that barley was the asset that sent the most net shock into the system. The EWR market in Turkey has come up recently. The market's structure, dynamics, and synchronization with other markets are still at a low level. The spillover effect of return and volatility shocks in the market are also low. The findings of this study can be used by producers, financial market participants and various decision makers for risk management, hedging and profit maximization purposes.Item Impacts of the First World War on Africa and Colonialism(2014) Erol, Mehmet Seyfettin; Bingol, Oktay; https://orcid.org/0000-0002-4794-5656; AAA-5129-2020The impacts of the First World War on Africa and the colonialism in Africa are a subject which is not sufficiently studied in the disciplines of political and military history, political science, and international relations.

Cenk; 0000-0002-2487-9553; J-8116-2015The concept of subjective well-being that is considered to be counterpart of the "happiness" in the psychological science is one of the indicators of how individuals think and sense their lifetime. The main purpose of this study is to explore the effects of the big five personality in the light of the genetic or personality theories and psychological capital with regards to the process or activity theories on the subjective well-being, and to seek for the mediating role of the psychological capital in this process.

The survey battery comprised of Well-being Scale, Big Five Personality Scale and Psychological Capital Scale. The data were analyzed with using Amos v20.0 and SPSS v20.0 programs. The findings showed a significant positive relationship between extraversion, agreeableness, psychological capital and subjective well being, and a significant negative relationship between neuroticism and subjective well being. In addition to that psychological capital mediated the relationship between the extroversion and subjective well being. The results allowed researchers to make casual inferences about the relationship between stable personality characteristics and psychological attributes indicated as intraindividual distal and proximal context in the well being literature.Item Paradoxical Leadership Model(2018) Basar, Ufuk; Basim, H. Nejat; 0000-0003-0008-5131; J-2510-2016; ABD-9381-2021The aim of this research is to develop a new theoretical leadership model, which explains the dark and bright sides of leadership with a holistic view, and thereby, to trigger a new debate through bringing in a new perspective to leadership phenomenon in the light of extant theories.
