Abstract:
This article aims to determine the academic disciplinary condition of Turkish terrorism studies in comparison to international ones. We first examine contemporary international terrorism studies and new trends, and then longitudinally assess Turkish terrorism studies via context and methodology. Last, we discuss how and through which perspectives the Turkish discipline could improve and thus contribute to the contemporary literature. We generated three datasets after examining theses, dissertations, and articles. Further, we conducted interviews with and administered questionnaires to terrorism experts to interpret the dataset findings. Regarding context, the most striking point of the Turkish research field is its multi-disciplinary character; because of this fact, Turkish terrorism studies tend to neglect the broader field’s terminology and theoretical accumulation. Regarding methodology, a significant problem in the terrorism studies in Turkey is that studies are mostly composed of literature reviews rather than empirical research, thus there is much opportunity for development.

Abstract:
Average treatment effects estimands can present significant bias under the presence of outliers. Moreover, outliers can be particularly hard to detect, creating bias and inconsistency in the semi-parametric ATE estimads. In this paper, we use Monte Carlo simulations to demonstrate that semi-parametric methods, such as matching, are biased in the presence of outliers. Bad and good leverage points outliers are considered. The bias arises because bad leverage points completely change the distribution of the metrics used to define counterfactuals. Whereas good leverage points increase the chance of breaking the common support condition and distort the balance of the covariates and which may push practitioners to misspecify the propensity score. We provide some clues to diagnose the presence of outliers and propose a reweighting estimator that is robust against outliers based on the Stahel-Donoho multivariate estimator of scale and location. An application of this estimator to LaLonde’s (1986) data allows us to explain the Dehejia and Wahba (2002) and Smith and Todd (2005) debate on the inability of matching estimators to deal with the evaluation problem.

13. Interrogating the “social life of methods” in critical approaches to security | Interroger la « vie sociale des méthodes » dans les approches critiques de la sécurité : expertise et enquête sur les questions de sécurité européenne

Abstract:
Research on the security politics of the European Union is becoming increasingly abundant. To further the aims of this special issue on methodology among critical approaches to security, this article draws on the appropriation by this scholarship of the “social life of methods” debate to open two related lines of investigation. First, the article examines the inscription of researchers into European security politics not only as a limit to research, but as a method of access and analysis. The article looks particularly at the identification of researchers as “experts” by EU practitioners, and at expertise as method. The second line of investigation and reflection concerns the limits inherent to the way in which critical scholarship on security has appropriated the “social life of methods” discussion. The article argues that this is an opportunity to engage with methods in relation to concrete research endeavors, rather than to stage a theoretical discussion on methods.

14. Analyzing the field of security in Switzerland: Towards a hypertrophy of internal security and some methodological remarks | Analyse du champ de la sécurité en Suisse : vers une hypertrophie de la sécurité intérieure et autres réflexions méthodologiques

Abstract:
Investigating the possible emergence of a transnational field of security in Europe constitutes a very stimulating research venue for literature on critical approaches to security. However, the operationalization of such an agenda entails some challenges. Notably, time-consuming data collection and analytical processes are needed in order to fully grasp the characteristics and resources of numerous actors. Drawing on a research project funded by the Swiss National Science Foundation (SNF), the aim of this paper is double. It offers both an analysis of the contemporary dynamics of the field of security in Switzerland and a presentation of practical solutions for researchers willing to conduct empirically-oriented studies of different settings of the transnational field of security in Europe. In order to do so, this contribution stands as a methodological roadmap, presenting the various steps leading to the construction of a national social space dedicated to “security issues”. Given the significant volume of data collected in this research project, a series of statistical analysis methods are mobilized in this paper: multiple correspondence analysis (MCA), principal component analysis (PCA), and network analysis. Lastly, in summarizing the project’s results, the paper points to the growing influence of transnational security dynamics on Swiss security actors.
