Effects of color and colored light on depth perception
(2010) Atlı, Deniz
The main purpose of this study is to understand the relationship between different objects and background colors, and depth perception in interior spaces. The experiment was conducted in two phases which consist of colored background light pairs (cool white-orange, cool white-blue, cool white-green, cool white-red, warm white-cool white, red-green and orange-blue) with colored objects (orange, blue and gray) in front of them. A forced choice paired comparison method was used to evaluate the differences in depth perception caused by colors. The participants were students who were having their internships in Philips Research Eindhoven, Netherlands. Firstly, participants were tested for color blindness and visual acuity, and the ones who passed these tests participated in the experiment. After the first phase of the experiment, a second part was required in order to obtain more accurate results. The participants who had internally consistent results in the first phase participated in the second phase of the experiment. In both phases, participants judged the distances of two same colored objects in front of colored lit background by choosing the one which they perceived as closer to themselves. As a result, differences between hues are smaller than the variations in perception of the participants, so hue has a really small effect on depth perception when evaluated monocularly.

Space, identity, and abjection : purification of Beyoğlu
(2011) Özakın, Emin Özgür
Beyoğlu provides uniquely rich material for a discussion on space and identity. Ever since its very foundation, the district has accommodated different nations, cultures, religions and architectural styles which were blended into a unique amalgam. Even if Beyoğlu fitted in the socio-political fabric of the Ottoman Empire, along with the Turkish modernization, there aroused a discontent over its identity. In the 20th century, Beyoğlu was turned into a contaminating element for the Turkish Republic and was subjected to various incidents that attempted to purify its complex identity. These incidents may well be read with Kristeva‟s “abjection”, a concept that serves in identity construction by simultaneously inventing and excluding an element of fear, revulsion, and hatred. Abjection towards Beyoğlu and its components were commonly masked by a nostalgic discourse that invented a pure bygone identity. In the 20th century, Beyoğlu has become a defiled resource, serving to perform and generate identities; but mostly chauvinist, nationalist, religious, and moralist ones. This fact necessitates a critical distance towards the essentialist view of identity construction operating with abjection, where the abject figure is merely regarded as something to be annihilated. Supported with an ethical dimension, post-structuralist ontology provides a non-violent and sustainable approach towards identity construction that necessarily includes the excluded.
