Köksal, Emre Ahmet

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 impacts of poststructuralism, psychoanalysis and postmodernism on the development of autofiction

Önder, Ayda

This study aims to investigate the ways in which poststructuralism, psychoanalysis and postmodernism have contributed to the development of autofiction. It is contended that the genre has a dialectical relationship with the twentieth century critical theories. Autofiction both affirms and questions the poststructuralist dismantling of the traditional perspectives on the concepts of authority, authenticity and truth by bringing the authorial presence back to the text but fictionalising it to some extent, committing to narrate the truth but creating an ambivalence around it. Autofiction engages ...Daha fazlası

The Quest of Women and revisionist mythmaking in muinar and the penelopiad: just voices or “just” voices?

Öner, Ayşe Ceren

The aim of the present study is to explore the emancipatory potential of revisionist mythmaking strategies employed in two contemporary novels, Margaret Atwood’s The Penelopiad (2005) and Latife Tekin’s Muinar (2006), through dialogic, intertextual, and deconstructive relations. Offering a comparative account by means of a three-fold theoretical basis between the two novels, this dissertation explores women’s paths to seek justice.

The philosophical position of Kant between neo-kantians and Heidegger kantian critique as protemetaphysica

Çılgın, Ozan

This study is based on a comparison of two interpretations which have been developed on Kant's philosophy. The first of these interpretations belongs to Heidegger and claims that Kant's philosophy is fundamentally an ontology, moreover a fundamental ontology based on the analysis of finite human whatness. He grounds this claim by arguing that Kantian criticism constitutes the subjectivity of the subject in a temporal context. Thus, the Kantian representation of the subjectivity of the subject emerges almost as an analytic of Dasein. The second interpretation belongs to the Marburg school of th ...Daha fazlası
