A Systematic Study to Understand the Effects of Particle Size Distribution of Magnetic Fingerprint Powders on Surfaces with Various Porosities

This study intends to design magnetite (Fe₃O₄)‐based magnetic fingerprint powders with different particle size distributions. It also investigates the influence of particle size distribution on the visualization of latent fingermarks with as little background staining as possible on the surfaces with various porosities in a systematic way. Two strategies were used to prepare the magnetic fingerprint formulations for this study: milling of coarse magnetite particles for different durations, and mixing of sieved fine particles with different size ranges with coarse particles. Particle size analyses of the prepared magnetic powders, optical microscopy‐based roughness analysis of the surfaces and SEM measurements of the visualized fingerprints and representative powders were performed. Mag2 of the formulations prepared through milling and Mag5 and Mag6 of the formulations prepared through sieving and mixing were more successful in the development of latent prints than the rest of the solutions.     

The Armed Peace: A Punctuated Equilibrium Theory of War

According to a leading rationalist explanation, war can break out when a large, rapid shift of power causes a credible commitment problem. This mechanism does not specify how inefficient fighting can resolve this cause, so it is an incomplete explanation of war. We present a complete information model of war as a sequence of battles and show that although opportunities for a negotiated settlement arise throughout, the very desirability of peace creates a commitment problem that undermines its likelihood. Because players have incentives to settle as soon as possible, they cannot credibly threaten to fight long enough if an opponent launches a surprise attack. This decreases the expected duration and costs of war and causes mutual deterrence to fail. Fighting's destructiveness improves the credibility of these threats by decreasing the benefits from continuing the war and can eventually lead to peace. In equilibrium players can only terminate war at specific windows of opportunity and fighting results in escalating costs that can leave both players worse off at the time peace is negotiated than a full concession would have before the war began.     

Born Weak,Growing Strong: Anti‐Government Protests as a Signal of Rebel Strength in the Context of Civil Wars

All rebel organizations start weak, but how do they grow and achieve favorable conflict outcomes? We present a theoretical model that allows for rebel organizations to gain support beyond their “core” and build their bargaining power during fighting. We highlight that rebel organizations need to win over crucial parts of society to generate the necessary support that allows them to attain favorable civil conflict outcomes. We find empirical support for the argument that low‐income individuals who initially fight the government (rebel organizations) have to convince middle‐class individuals to turn out against the government to gain government concessions. Empirically, we demonstrate that government concessions in the form of peace agreements and the onset of negotiations become more likely when protest occurs in the context of civil conflicts.

The View from Next Door: Greek-Turkish Relations after the Coup Attempt in Turkey

ABSTRACT

Turkey’s recent slide into authoritarianism will have implications for its close neighbours in the West. Especially Greece cannot avoid negative spill-over effects. A coalition government comprising Syriza and Independent Greeks does not have an unconstrained set of policy choices in responding to this. Maintaining effective working relations is a paramount interest but achieving this is easier in principle than in practice especially considering the issues of asylum seekers and Turkish revisionism on the Lausanne Treaty. Unlike the two parties that dominated the Greek political scene after 1974, PASOK and New Democracy, the current government has little experience navigating choppy diplomatic seas with Turkey.     

Tailoring Strategies According to Ever-Changing Dynamics: The Evolving Image of the Kurdish Diaspora in Germany

Germany might be considered as the European country that has suffered the most from the spatial diffusion of Turkey's internal conflicts. It has received the highest number of Kurdish migrants in Europe and it became the core of Kurdish mobilization in transnational space. Germany's approach to the Kurdish Question on its own soil—combined with the strategies that the Kurdish activists used—determined the scope of opportunity structures for the mobilization of the Kurdish movement. This article explains how Kurdish activism has come to be perceived in Germany, and analyzes the German political environment by focusing on the criminalization and stigmatization of the Kurdish movement, especially during the 1990s. It then describes the discursive shift and change in framing strategies that the Kurdish diaspora experienced after the capture of the the Kurdistan Workers' Party's (PKK) leader in 1999. Lastly, it touches upon the recent developments in the Middle East, especially in Kobane, and their impact on the image of the Kurdish movement. The article is based on extensive fieldwork in Germany and includes testimonies of Kurdish diaspora activists, with a focus on their own perceptions about their situation and how they respond to securitization policies in the host country.     

“Academics for Peace” in Turkey: a case of criminalising dissent and critical thought via counterterrorism policy

ABSTRACT

On 11 January 2016, 1128 academics in Turkey and abroad signed a petition calling on Turkish authorities to cease state violence in mainly Kurdish populated areas of the country, which had been under curfew and an extended state of emergency. The petition received an immediate reaction from President Recep Tayyip Erdo?an, who accused the signatories of treason and terrorist propaganda. He subsequently demanded that public prosecuters launch an investigation. Criminalisation of the petition has been exacerbated by disciplinary action by universities against many of the signatories. Many have suffered insults, arrest, detention or suspension as a result of the ensuing smear campaign. This massive crackdown on academic freedom has been masked by discourses of counterterrorism, which have also been deployed to criminalise dissent more generally in Turkey as a part of a process of rapid “democratic retrenchment” since 2013. This article is an attempt to put the criminalisation of academics within the larger framework of human rights violations, increasing curtailments of academic freedom and rising authoritarianism in Turkey. It argues that the prosecution of the signatories of the petition is an extension of an established tradition of targeting academic freedom in times of political crisis in Turkey but is also a product of growing authoritarianism under the ruling party and President Erdo?an. It shows that counterterrorism laws can be extended far beyond eliminating security threats by instrumentalising them to suppress dissent in a declining democracy.
