In this paper, realized volatility of a selection of BIST Indices are forecasted with Heterogeneous Autoregressive Model (HAR) and its variations. For this purpose, ticks between 2001 and 2021 are used to generate 5-minute returns, which formed the basis for calculations of realized volatility and other realized measures. In the study, rolling windows are utilized for forecasting the volatility of one day ahead. These predictions are then compared to the actual realized volatilities. The study provides a thorough comparison of HAR-type models, and emphasizes the importance of underlying time s ...Daha fazlası

The aim of this thesis is to propose a hypothetical community for queer people of 20th century England depicted in two novels: Radclyffe Hall’s The Well of Loneliness (1928) and Jeanette Winterson’s Oranges Are Not the Only Fruit (1985) through Agamben’s idea of community. This study also intends to investigate the issue of the queer people in the 20th century, while demonstrating that the oppression of homosexual people has not changed despite the fact that one of the two novels is written at the beginning and the other at the end of the twentieth century. Suggesting a community to the queer ...Daha fazlası
The introduction of electronic image recording tools in the 1950s provided a unique structure that could affect the production processes of artists. At the beginning, video art was used by artists to criticize television and later on, artists developed new strategies using the possibilities of video from different disciplines and perspectives. Since 1960, artists have started to use video as a means of expression and video has spread rapidly. In Turkey, the spread of video art coincided with the 1990s, and the interest of artists in video art increased in the 2000s. The elements to be consider ...Daha fazlası
The global value chain has increased its importance with the spread of foreign trade between countries. As a result of this situation, it has provided serious economic returns to the countries. Countries that use the global value chain effectively have become rich in this process. In this study, the comparison of foreign trade between BRIC countries and Turkey has been examined through Grubel Lloyd index. Through this Grubel Lloyd index, the economic effects of the global value chain on the Turkish economy and BRIC countries are detailed. The increasing importance of global value chain, which ...Daha fazlası
This thesis study examines the conditions that laid the groundwork for art funds in particular, their formation and development processes, and subsequently analyses the properties of art funds as a type of investment fund, and their structure and diversity, ultimately closely examining their investment strategies in detail through examples. Although artworks have been known to be valuable for centuries, the classification and acceptance of artworks as an asset class is a newer phenomenon that occurred in the last century. The operating mechanisms unique to the art markets evolved within the li ...Daha fazlası
Regardless of the cultural differences, the 19th century Victorian England and Tanzimat Period in Ottoman Empire had similar expectations from women. The two novelists from these two countries, Thomas Hardy and Ahmet Mithat Efendi, had critical attitude towards such expectations. Thus they created socially unacceptable but acceptable for them heroines. Afterall, for some Sue Bridehead is Hardy’s main focus and similarly for Ahmet Mithat Raziye is still an angel. The reason why these two heroines are unacceptable for the society’s of their days is intriguing. Considering all these, the aim of t ...Daha fazlası

Over 60 days (April 1st - May 31st, 2023), an online survey gathered 300 comprehensive responses, revealing substantial insights, and 4 interviews have been conducted with 4 volunte ...Daha fazlası
Advances in machine learning in recent years have also been seen in computationally creative systems. Interest in machine-generated artifacts paved a way for creative models to evolve as such. But the earlier methods mostly explored a one domain approach and cross-modal learning has stayed relatively unexplored. Thus, the direct mapping between modalities for cross-modal creative models is not fully explored. This work proposes a novel methodology for generating symbolic music through images by directly mapping their features. A CNN encoder and deep stacked LSTM decoder are the base models as ...Daha fazlası
Migration has always been a way for people to reach a better life and a strategy to adapt to changing conditions. Since the early 1000s, climate-related environmental changes have begun to directly impact communities whose way of life is dependent on nature and local resources. Owing to climate change, which is mostly a result of human activity, and the devastating environmental changes it has created, people have begun to relocate voluntarily or forcefully, to abandon their homelands, and these migrations within the country or across borders are now evident. The International Organization for ...Daha fazlası
