A sociological study on young people’s value differences from their parents along the materialist/postmaterialist axis

Öksüz, Nuran

This study aims to discover the challenges for secular middle-class youth in Turkey with materialist-postmaterialist value differences with their parents climbing the social ladder. The fact that the focused group is comparatively more advantageous than the lower-income groups in terms of socioeconomics can make their problems invisible. In this respect, the subject of this study has not been adequately covered in the literature, and it is crucial to study. The study used the in-depth interview method, and eight young people between the ages of 20 and 30 were reached with snowball sampling. Si ...Daha fazlası

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

Status of Ilkhan in the socio-political organization of the Qashqai Tribe

Sohrabi, Hossein

This anthropological research is related to the Qashqai tribe, which lives in southwestern Iran, and apart from the urban and rural population, it has nearly 96,500 nomadic people. This research answers the question, could the Qashqais have the same solidarity, authority, and integrity without an Ilkhan from the Shahilu family? My claim is based on the fact that the main factor of Qashqai solidarity and empowerment in southern Iran, where the majority of the population is Tajik and non-Turkish, was the Ilkhans from the Shahilu family. And with the leadership of the Shahilu family, the Qashqais ...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

The impact of instagram on risks of developing eating disorders: Young female adults and appearance-focused accounts

Gad, Toka

The prevalence and extensive usage of Instagram as a social media platform have drawn my attention to the issue of appearance-oriented accounts on Instagram that endorse unrealistic standards of beauty. These accounts may contribute to the development of eating disorders, especially among young adult women. Various studies consistently indicate a connection between exposure to idealized depictions of female beauty in the media and negative effects on mood, self-esteem, body dissatisfaction, and a desire to be thin. Recent research has specifically focused on appearance-oriented accounts on Ins ...Daha fazlası
