The complexity of many cases, such as public projects and programs, requires evaluation methods that acknowledge this complexity in order to facilitate learning. On the one hand, the complexity of the cases derives from their uniqueness and nested nature. On the other hand, there is a need to compare cases in such a way that lessons can be transferred to other (future) cases in a coherent and non-anecdotal way. One method that is making headway as a complexity-sensitive, comparative method is Qualitative Comparative Analysis (QCA). This contribution aims to explain to what extent QCA is complexity-informed, to show how it can be deployed as such, and to identify its strengths and weaknesses as an evaluation method. We will discuss the properties of complexity, provide an overview of evaluation literature about QCA, and present a simplified step-wise guide for utilizing QCA in evaluation studies.
Gecekondu are informal settlements that have been at the heart of the rapid urbanisation of modern Turkey, especially in Istanbul and Izmir. Gecekondu squatting started in the 1940s as a need-oriented practice of poor rural migrants who needed cheap accomodation in Turkey's growing cities. Over time, gecekondu neighborhoods were legalized, and their dwellers became part of the urban middle class by erecting apartment buildings on their plots. In the 1980s, it became common to buy, and later to steal, privately owned agricultural land in order to construct apartment buildings on it. Appropriation was no longer geared towards need, but towards profit.
Appropriation of state-owned (agricultural) land was already a common practice in Ottoman times, and so was rural work migration to major cities, such as Istanbul and Izmir. In the aftermath of the Armenian Genocide and the Population Exchange with Greece, private property of Armenians and Greeks was appropriated and squatted by Muslims. This article argues that these historical precedents informed the way in which gecekondu dwellers legitimated their need-oriented appropriation of state land. With the arrival of neoliberalism, however, appropriation of state property no longer served to alleviate poverty, but became big business. Today, it is major real estate firms and the state-owned public housing authority (TOKI) that privatize state land in order to build gated communities for the upper middle class.
Cognitive behavioral models postulate that selective attention plays an important role in the maintenance of body dysmorphic disorder (BDD). It is suggested that individuals with BDD overfocus on perceived defects in their appearance, which may contribute to the excessive preoccupation with their appearance.
The present study used eye tracking to examine visual selective attention in individuals with BDD (n = 19), as compared to individuals with bulimia nervosa (BN) (n = 21) and healthy controls (HCs) (n = 21). Participants completed interviews, questionnaires, rating scales and an eye tracking task: Eye movements were recorded while participants viewed photographs of their own face and attractive as well as unattractive other faces.
Eye tracking data showed that BDD and BN participants focused less on their self-rated most attractive facial part than HCs. Scanning patterns in own and other faces showed that BDD and BN participants paid as much attention to attractive as to unattractive features in their own face, whereas they focused more on attractive features in attractive other faces. HCs paid more attention to attractive features in their own face and did the same in attractive other faces.
Results indicate an attentional bias in BDD and BN participants manifesting itself in a neglect of positive features compared to HCs. Perceptual retraining may be an important aspect to focus on in therapy in order to overcome the neglect of positive facial aspects. Future research should aim to disentangle attentional processes in BDD by examining the time course of attentional processing.
