Publication Open Access Evolutionary multiobjective feature selection for sentiment analysis(Institute of Electrical and Electronics Engineers (IEEE), 2021) Pelin Angın; Deniz, Ayça; Department of International Relations; Angın, Merih; Faculty Member; Department of International Relations; College of Administrative Sciences and Economics; 308500Sentiment analysis is one of the prominent research areas in data mining and knowledge discovery, which has proven to be an effective technique for monitoring public opinion. The big data era with a high volume of data generated by a variety of sources has provided enhanced opportunities for utilizing sentiment analysis in various domains. In order to take best advantage of the high volume of data for accurate sentiment analysis, it is essential to clean the data before the analysis, as irrelevant or redundant data will hinder extracting valuable information. In this paper, we propose a hybrid feature selection algorithm to improve the performance of sentiment analysis tasks. Our proposed sentiment analysis approach builds a binary classification model based on two feature selection techniques: an entropy-based metric and an evolutionary algorithm. We have performed comprehensive experiments in two different domains using a benchmark dataset, Stanford Sentiment Treebank, and a real-world dataset we have created based on World Health Organization (WHO) public speeches regarding COVID-19. The proposed feature selection model is shown to achieve significant performance improvements in both datasets, increasing classification accuracy for all utilized machine learning and text representation technique combinations. Moreover, it achieves over 70% reduction in feature size, which provides efficiency in computation time and space.Publication Open Access How do mega-bank merger policy and regulations contribute to financial stability? Evidence from Australia and Canada(Taylor _ Francis, 2017) Department of International Relations; Bakır, Caner; Faculty Member; Department of International Relations; College of Administrative Sciences and Economics; 108141Although the role of financial regulatory failures in the global financial crisis (GFC) has been explored extensively in the post-GFC literature, our knowledge of the role of bank merger and takeover policy and regulation in reinforcing financial stability is limited. Based on an exploratory case study of Australia, which is examined in comparison to Canada, this article argues that competition policy and regulation contributed to financial stability by insulating the largest Australian and Canadian banks from domestic or foreign hostile takeover threats, and by limiting their asset size, and thus their internationalization and interconnections with the global banking community.Publication Open Access Turkey's two elections: the AKP comes back(Johns Hopkins University (JHU) Press, 2016) Öniş, Ziya; Department of International Relations; Faculty Member; Department of International Relations; College of Administrative Sciences and EconomicsIn power since 2002, the Justice and Development Party (AKP) of Recep Tayyip Erdoğan seemed as if it might be losing its hold when Turkish voters went to the polls in June 2015. Yet that “hung election” gave way to another contest in November, and the AKP came roaring back.Publication Open Access Turkish foreign policy in a post-western order: strategic autonomy or new forms of dependence?(Oxford University Press (OUP), 2021) Kutlay, Mustafa; Department of International Relations; Öniş, Ziya; Faculty Member; Department of International Relations; The Center for Research on Globalization, Peace, and Democratic Governance (GLODEM) / Küreselleşme, Barış ve Demokratik Yönetişim Araştırma Merkezi (GLODEM); College of Administrative Sciences and Economics; 7715Turkish foreign policy has dramatically transformed over the last two decades. In the first decade of the Justice and Development Party's (AKP) rule, the 'logic of interdependence' constituted the driving motive of Turkish foreign policy. In the second decade, however, the 'logic of interdependence' and the soft power-driven 'mediator-integrator' role were gradually replaced with a quest for 'strategic autonomy', accompanied by interventionism, unilateralism and coercive diplomacy. This article explores the causes of this dramatic shift. We argue that 'strategic autonomy', which goes beyond a moderate level of status-seeking compatible with Turkey's material power credentials, has a double connotation in the Turkish context. First, it constitutes a framework for the Turkish ruling elite to align with the non-western great powers and balance the US-led hierarchical order. Second, and more importantly, it serves as a legitimating foreign policy discourse for the government to mobilize its electoral base at home, fragment opposition and accrue popular support. We conclude that the search for autonomy from its western allies and the move towards the Russia-China axis has led to Turkey's isolation and permitted the emergence of new forms of dependence.Publication Open Access Parliamentary elections and the prospect for political pluralism in North Africa(Cambridge University Press (CUP), 2000) Department of International Relations; Dillman, Bradford L.; Department of International Relations; College of Administrative Sciences and EconomicsPublication Open Access Introduction to the special issue anxiety and change in international relations(International Relations Council of Turkey (IRCT) / Uluslararası İlişkiler Konseyi Derneği, 2022) Department of International Relations; Rumelili, Bahar; Faculty Member; Department of International Relations; College of Administrative Sciences and Economics; 51356Publication Open Access Discourse analysis: strengths and shortcomings(Center for Foreign Policy and Peace Research, 2019) Aydın-Düzgit, Senem; Department of International Relations; Rumelili, Bahar; Faculty Member; Department of International Relations; College of Administrative Sciences and Economics; 51356Discourse analysis is a much-favoured textual analysis method among constructivist and critically minded International Relations scholars interested in the impact of identity, meaning, and discourse on world politics. The aim of this article is to guide students of Turkish IR in their choice and use of this method. Written by two Turkish IR scholars who have employed discourse analysis in their past and present research, this article also includes a personal reflection on its strengths and shortcomings. The first section of the article presents an overview of the conceptual and epistemological underpinnings of discourse analysis, while charting the evolution of discourse analysis in IR since the late 1980s in three phases. The second section offers insight into the personal history of the researchers in employing discourse analysis in their previous and ongoing research, while the third section provides a how-to manual by performing discourse analysis of an actual text. The concluding section focuses on the challenges faced in the conduct of discourse analysis and the potential ways to overcome them, also drawing from the researchers'own experiences in the field.Publication Open Access Why some countries are immune from the resource curse: the role of economic norms(Taylor _ Francis, 2016) Mousseau, Michael; Department of International Relations; Aytaç, Selim Erdem; Örsün, Ömer Faruk; Faculty Member; Department of International Relations; College of Administrative Sciences and Economics; 224278; N/AThe political resource curse - the detrimental effect of natural resource dependence on democracy - is a well-established correlate of authoritarianism. A long-standing puzzle, however, is why some countries seem to be immune from it. We address this issue systematically by distinguishing two kinds of economies: contract-intensive, where individuals normally obtain their incomes in the marketplace; and clientelist, where individuals normally obtain their incomes in groups that compete over state rents. We theorize that the institutionalized patronage opportunities in clientelist economies are an important precondition for the resource curse, and that nations with contract-intensive economies are immune from it. Analysis of 150 countries from 1973 to 2000 yields robust support for this view. By introducing clientelist economy as a prerequisite for the resource curse, this study offers an important advance in understanding how nations democratize.Publication Open Access Bridging international political economy and public policy and administration research on central banking(Taylor _ Francis, 2021) Yağcı, Mustafa; Department of International Relations; Bakır, Caner; Faculty Member; Department of International Relations; College of Administrative Sciences and Economics; 108141Central banking as an avenue of research has been of interest to scholars from International Political Economy (IPE) and Public Policy and Administration (PPA) disciplines. Nevertheless, there is very little dialogue between these two perspectives to bridge macro, meso, micro-level analyses and examine the reciprocal relationship between the global and domestic political economy context and monetary policy conduct. This article investigates the Turkish experience to bridge IPE and PPA scholarship on central banking in emerging economies. In doing so, we adopt an analytic eclectic approach combining multiple structural, institutional, and agential causal explanations with particular reference to the Structure, Institution, and Agency (SIA) theoretical framework. This is because analytic eclecticism complements, speaks to, and selectively incorporates theoretical approaches such as the New Independence Approach (NIA) of IPE and institutional and ideational PPA approaches. Drawing on the empirical context of the historical evolution of the Turkish political economy, we explore domestic and international interactions among micro, meso, and macro levels that shape central banking behavior. Our analysis also reveals how global dynamics are translated into domestic policy choices and how particular ideas influence the policymaking process. The analysis underscores the constraining and enabling influence of international dynamics, politics of ideas on emerging economy central banking, and the essential role individual and organizational agency play in the policymaking process.Publication Open Access Making and unmaking culture: gender experts, faith, and the international governance of gender(Routledge, 2021) Department of International Relations; Olcay, Özlem Altan; Faculty Member; Department of International Relations; College of Administrative Sciences and EconomicsThis article explores the workings of gender expertise inside the institutions of the international governance system as it engages with faith-based actors. Utilizing narratives of gender experts, documentary analysis, and observation, I focus on these experts’ encounters regarding gender equality and women’s rights with religious leaders, religious actors, and conservative governments. Focusing on episodes in which the terms “cultural difference” and “religion” are used synonymously, first, I show how encounters between transnational actors can play a role in hegemonic interpretations of these terms. Second, I explore how powerful actors can become more authoritative in making claims of cultural difference or how the existing distribution of power may be disrupted. I contend that these power relations affect discussions of gender equality. My goal is to contribute to feminist debates by highlighting the ways in which these transnational interactions disrupt assumptions of West versus East. Paying attention to these complex processes can challenge ethnocentric and racist discourses without taking claims of cultural difference at face value.
