Furtana, Beyza
This study investigates the physical and rheological properties of asphalt binders recovered from earthquake damaged road sections in Hatay, Kahramanmaras, Gaziantep, and Malatya following the February 6, 2023, earthquakes in southern Türkiye (Mw = 7.8 and Mw = 7.5). Asphalt mixture samples were collected from severely deteriorated pavements, and bitumen was extracted through solvent extraction and rotary evaporation. The recovered binders were subjected to penetration, softening point, rotational viscosity, and Dynamic Shear Rheometer (DSR) tests to evaluate aging, stiffness, high-temperature performance, and viscoelastic behavior. Results revealed significant regional differences: Hatay binders exhibited the lowest penetration, highest softening point, highest viscosity, and the greatest rutting resistance (high G*/sinδ values) while maintaining lower phase angles, indicating enhanced stiffness and elasticity. In contrast, Kahramanmaras binders showed the highest penetration, lowest softening point, and lower viscosity, combined with high phase angles, reflecting a softer, more viscous character with reduced deformation resistance. Malatya and Gaziantep binders displayed intermediate characteristics, with Malatya showing moderate stiffness and Gaziantep retaining greater flexibility. Across all samples, viscosity decreased markedly with increasing temperature, and rutting resistance diminished at higher service temperatures; however, binders with higher initial G*/sinδ values retained better performance. The findings highlight the influence of regional seismic intensity, climatic conditions, and pavement history on binder behavior and emphasize the need for region-specific maintenance and rehabilitation strategies in post-disaster pavement management.

Şentürk, Gamze
Sex and gender are two concepts that are often unconsciously used interchangeably, but they have distinct meanings. They are crucial in understanding the gender hierarchy or the distinction between man and woman created by the patriarchal order. While sex refers to a biological difference or an innate existence based on signs such as chromosomes and genitals, gender is a socio-cultural identity subsequently acquired through social interaction. While the biology-oriented approach reduces femininity and masculinity to the body based on an essentialist approach, the socio-culturally oriented approach underlines that femininity and masculinity are culturally constructed, fluid, and changeable. The gender roles assigned to man and woman in patriarchal society bring along certain expectations based on their sexes and their society’s values and beliefs about gender. The fact that both woman and man are expected to wear appropriate dress for their gender roles is the reflection of this expectation. When a man wears clothing traditionally associated with women or when a woman wears clothing traditionally associated with men, they might face ridicule or criticism because these clothing choices challenge established gender norms, and because the clothes are reminders of roles or symbols that favour social roles. Contrary to this, cross-dressing is described as an act of wearing clothes and accessories that belong to the opposite sex, and it is possible to see its examples as a deconstructive strategy in contemporary British feminist theatre. This article aims at discussing the functions of cross-dressing as a body memory in contemporary British feminist theatre over selected plays such as Caryl Churchill’s plays Cloud Nine (1979) and Top Girls (1982), Timberlake Wertenbaker’s New Anatomies (1984), and Moira Buffini’s Silence (1999).
