Americanization of Political Campaigns: a Comparison of the Cases of Forza Italia and the Young Party
(Turkiye Orta Dogu Amme Idaresi Enstitusu, 2010) Turk, Hasan Bahadir; Türk, Hasan Bahadır; Siyaset Bilimi ve Uluslararası İlişkiler
Similar to political institutions and structures, political campaigns have also undergone dramatic transformations. The Americanization of political campaigns, which are characterized by certain peculiarities, such as the personalization of politics, weakening of party organizations, wide use of media channels in the political marketing process, need for specialization, primacy of opinions over ideologies and conceptualization of citizens as policy consumers, is a by-product of these dramatic transformations. This paper aims to compare Forza Italia and the Young Party through the Americanization of political campaigns with special emphasis on the connection between the transformation of political campaigns and the crisis of representative democracy.

An Alternative Mean Reversion Test for Interest Rates
(Central Bank Republic Turkey, 2018) Ozel, Ozgur; Ilalan, Deniz
A number of empirical studies assert that interest rates are governed by unit root processes rejecting any form of reversion to a long term mean by resorting to certain tests, among which the Augmented Dickey Fuller (ADF) is the most widely used one. In this study, we propose an alternative testing methodology that can be applied along with ADF test, in the sense that there are times where it can capture stationarity when the other fails to do so. Moreover, our test has more power than ADF test. As an application to real-data, we consider 10-year US and Turkish T-bond rates. (C) 2017 Central Bank of The Republic of Turkey.

Analysis of Distinct Asymmetries in Financialintegration-Growthnexus for Industrial, Emerging and Developing Countries
(Wiley, 2022) Ocal, Nadir; Yolcu Karadam, Duygu
This paper examines the threshold conditions in financial integration and growth relationship for a large set of threshold variables and different income group of countries employing Panel Smooth Transition Regression Models. Except developing countries, our findings strongly indicate nonlinear dynamics and imply that the impact of financial integration on growth is asymmetric depending on a number of indicators such as countries' degree of institutional quality, financial sector development, trade openness, budget deficit, inflation volatility and the level of financial integration. Our results show that these threshold effects substantially differ for emerging and industrial countries. As far as whole set of countries is concerned, our findings imply that countries having developed financial systems, qualified institutions and stable macroeconomic environment benefit from financial integration. Moreover, threshold effects are stronger and different for emerging countries compared to the industrial countries. Unlike emerging economies, higher levels of financial integration and trade openness decrease benefits from financial openness for the industrial countries. Besides, high fiscal deficit has more pronounced negative effect on the growth of the industrialized countries compared to emerging economies and other indicators.
Asymmetric Smooth Transition in Cds Spreads: Evidence From Latvia
(Allied Business Academies, 2019) Akdoğan, E.C.; Akdoğan, Ece Ceylan; Bankacılık ve Finans
This paper investigates the predictability of CDS premiums and thus addresses weak form informational efficiency of CDS markets through examining the statistical properties of Latvian CDS spreads in-between 01:2006-08:2017 by concentrating on stationarity issues. The findings for the Augmented Dickey Fuller test fail to reject the presence of unit root indicating that the CDS market is weak form efficient while nonlinear tests of Kapatenios, Snell and Shin, and Sollis claim the opposite, demonstrating a smooth transition in general, and asymmetric smooth transition in particular. Additionally, the results of Perron and Zivot-Andrews tests identify no structural break as well for robustness. These results underline the necessity of accounting for nonlinearities in CDS premiums to grasp the predictability dynamics better. © 2019, Academy of Accounting and Financial Studies Journal.
At the Convergence of Energy Corridors: Energy Situation in Turkey and a Critical Evaluation With Porter's Model
(Igi Global, 2017) Gokmen, Aytac; Nakip, Mahir
Turkey is at the threshold of Eurasia connecting various energy corridors. It has an improving economic volume and is one of the 20 largest economies in the world. Energy and economic development are highly correlated. Turkey is dependent on imported energy. In order to keep up with the economic expansion, the energy requirements of Turkey must be met in a diversified, timely and reliable way. Thus, the aim of this paper is to define the geographic disposition of Turkey at the convergence of energy lines, review its energy situation comprehensively and make critical evaluations on energy and economy related issues, also with using the diamond model developed by Michael E. Porter resting on credible national and international publications and data.

Bitcoin Market Price Analysis and an Empirical Comparison With Main Currencies, Commodities, Securities and Altcoins
(Springer Science and Business Media Deutschland GmbH, 2019) Dinçergök, B.; Haşlak, Ş.; Pirgaip, B.
The purpose of this study is to analyze Bitcoin (BTC) market prices and to answer the question of whether there is a relationship between BTC and other asset prices, where other assets include currencies, commodities, securities and altcoins. In the empirical part, we evaluate the lead-lag relationships among each type of asset. Consequently, we compare BTC with major currencies and stock exchanges of the U.S., the EU, the U.K. and Japan (USD-SPX, EUR-DAX, GBP-FTSE and JPY-NIK), with currencies and stock exchanges of the U.S., the U.K., Russia, Venezuela and China where BTC is actively traded (USD-SPX, GBP-FTSE, RUB-MOEX, VEF-IBVC and YUAN-SSCE), with major commodities (GOLD and OIL) and with major altcoins (ETH, XRP and LTC) on a daily basis for the period spanning from 2010.07 to 2018.12. We employ Johansen co-integration, Granger causality, impulse response functions and forecast error variance decomposition analyses in our study. Our results show that BTC does not have a long-run relationship with any asset type, but that it has a short-run relationship with gold and especially altcoins, which are both significant and bidirectional. While BTC and altcoins are closely interrelated with each other, BTC price variation is mostly borne by its own prices in all cases. © Springer Nature Switzerland AG 2019.

Board Composition and Organizational Performance: Environmental Characteristics Matter
(Elsevier Science Bv, 2011) Varoglu, Abdulkadir; Aren, Selim; Sener, Irge
Concern for board of directors considerably increased with the recent developments in the corporate governance field. Despite that extensive research was conducted, the understanding of the board and its effects is still limited. This is mainly because that the majority of the corporate governance research focused mostly on the direct relation of board characteristics with organizational outcomes, and neglected the effect of intervening variables, leading to inconclusive research findings. Deriving on this limitation, in this study, the effect of board composition on organizational performance was investigated for different environmental conditions, which are measured in terms of munificence and dynamism of the industry in which the organizations operate and product complexity of the organizations. In addition, the moderating effects of these dimensions of organizational task environments on the relationship between board composition and organizational performance were also addressed. Building on resource dependence theory, it is suggested that under different environmental conditions, different compositions of boards will positively influence organizational performance. Based on the data from 80 companies which shares are publicly traded in Istanbul Stock Exchange, the findings indicate that the effect of board composition on organizational performance vary among different environmental conditions.

Business Groups and Internal Capital Markets
(Routledge Journals, Taylor & Francis Ltd, 2007) Gonenc, Halit; Kan, Ozgur B.; Karadagli, Ece C.
We compare the performance of firms affiliated with diversified business groups with the performance of unaffiliated firms in Turkey, all emerging market. We address the question of whether group-affiliated firms create internal capital markets or control large cash flows. Our findings indicate that group affiliation improves a firm accounting performance, but not stock market performance. Deviation of cash-flow rights front voting rights has a negative but insignificant effect on accounting performance, but a significant effect on market performance. We also find that a firm's accounting, but not stock market, performance increases with the level of group diversification. Our results show that internal capital markets play an important role for the existence of business groups in all emerging market context.
A Case Study: Internet Based Collaborative and Cooperative Learning
(int inst informatics & Systemics, 2007) Demirbulak, Dilara; Aşkun, Ali Rıza; Demirbulak, Dilara; Askun, Ali Riza; Ortak Dersler Bölümü; İngiliz Dili ve Edebiyatı
The Internet has improved the quality and quantity of communication all over the world by providing opportunity to electronically deliver and share knowledge instantly all over the world. As for the impact of this on education the ones relevant for this study are the need to integrate educational technology and collaborative learning into curriculum. This is the third phase of a longitudinal study. It was carried out at an English Language Teacher Training Certificate Program, "Methodology" course at a Higher Education institution. The same course was being given by one instructor to two different groups of learners who had not met each other. Each week a different method was focused on by different groups of learners. Each group presented the principles of the method using the method itself and then discussions were carried out. The presentations were video-taped and discussions were carried out based on key points presented via power-point. The learners in the two courses focusing on the same methodology were asked to interact by means of the internet and their output was evaluated, Based on the results of data gathered it could be said that virtual teams learner outputs were, effective and in some cases were more effective than the face to face teams.

Cointegration, Causality and the Transmission of Shocks Across Wheat Market in Pakistan
(Springer, 2009) Klasra, Mushtaq Ahmad
This paper uses quarterly price data and examines the transmission of shocks across different spatially separated locations besides identifying causality among these locations. Johansen and Juselius's (Econ. Stat., 52, 160-210, 1990) multivariate cointegration procedure identified two cointegrating vectors among these locations. Following Toda and Yamamoto (J. Econom., 66, 225-250, 1995), causality tests showed only one bi-directional causality and it was between Peshawar and Hyderabad locations. Faisalabad and Sargodha appeared independent (i.e. exogenous) market locations in price discovery process. Peshawar market showed maximum (i.e. 5) number of significant links. The generalized impulse response functions, though, suggested similar (cyclical) pattern of responses across the markets, but their time profile, which provides insight into the system's speed of convergence to long run equilibrium path, varied with different level of extent and persistency. Responses to shock originating in consumption markets (i.e. Karachi, Peshawar and Lahore) remained short lived; whereas the shocks stemming from surplus wheat producing locations (i.e Multan, Sargodha and Faisalabad) produced long and more persistent responses.

A Comparative Civilizational Reading for the Middle East and Turkey's New Role in It
(Routledge Journals, Taylor & Francis Ltd, 2016) Atac, C. Akca
The 1990s witnessed a bloom of studies on the standard of civilization', which all aimed to explore the future of the rift between the East and the West. The Arab Spring and its implications for the primordial competition between the East and the West has once again required the revisiting of certain, rather more contemporary, theoretical aspects of the grand debate on civilization. This paper aims to introduce current arguments pertaining to the grand debate on civilization into the context of the Arab Spring. In doing so, it seeks to offer a comparative perspective of the quest for understanding the current situation in the Middle East with particular reference to the civilization discourse which is currently on the rise in Turkish politics. Turkey is among the actors in the Middle East seeking to assume leadership in order to establish peace in the region.

Competitiveness of Major Exporting Countries and Turkey in the World Fishery Market: a Constant Market Share Analysis
(2005) Fidan, H.; Klasra, M.A.
The purpose of this study is to examine whether and to what extent the shares of selected countries' fishery exports in the world markets reflect their international competitiveness. The Constant Market Share (CMS) model, which decomposes export growth into some broad components (i.e., structural effects, market effects, commodity effects and competitive effects), is applied to examine this issue. The results of decomposition analysis revealed that structural factors have been more significant in explaining the growth of exports. The growth effects, though, appeared positive for each country, the exports of open economies like Canada, the United States, Iceland and Turkey benefited more from the growth of world exports. The analysis of commodity composition and market effects suggests that countries like Canada, the United States, Iceland and Turkey were pursuing the product differentiation policy and were penetrating in those markets, which have been growing relatively faster. These countries remained committed throughout the sample period (i.e., 1980-2000) to export their diversified products in fast-growing markets. The analysis of competitiveness effects, which are derived as a residual, show that Norway, Spain, the United States, Indonesia, Thailand, sChile and China were strong fishery exporters and increased their competitiveness during the sample period.

Computing Non-Stationary (S, S) Policies Using Mixed Integer Linear Programming
(Elsevier Science Bv, 2018) Xiang, Mengyuan; Rossi, Roberto; Martin-Barragan, Belen; Tarim, S. Armagan
This paper addresses the single-item single-stocking location non-stationary stochastic lot sizing problem under the (s, S) control policy. We first present a mixed integer non-linear programming (MINLP) formulation for determining near-optimal (s, S) policy parameters. To tackle larger instances, we then combine the previously introduced MINLP model and a binary search approach. These models can be reformulated as mixed integer linear programming (MILP) models which can be easily implemented and solved by using off-the-shelf optimization software. Computational experiments demonstrate that optimality gaps of these models are less than 0.3% of the optimal policy cost and computational times are reasonable. (C) 2018 Elsevier B.V.

Confidence-Based Reasoning in Stochastic Constraint Programming
(Elsevier, 2015) Rossi, Roberto; Hnich, Brahim; Tarim, S. Armagan; Prestvvich, Steven
In this work we introduce a novel approach, based on sampling, for finding assignments that are likely to be solutions to stochastic constraint satisfaction problems and constraint optimisation problems. Our approach reduces the size of the original problem being analysed; by solving this reduced problem, with a given confidence probability, we obtain assignments that satisfy the chance constraints in the original model within prescribed error tolerance thresholds. To achieve this, we blend concepts from stochastic constraint programming and statistics. We discuss both exact and approximate variants of our method. The framework we introduce can be immediately employed in concert with existing approaches for solving stochastic constraint programs. A thorough computational study on a number of stochastic combinatorial optimisation problems demonstrates the effectiveness of our approach. (C) 2015 Elsevier B.V. All rights reserved.

A Content Analysis of Sustainable Development in the Tourism Literature
(Taylor and Francis, 2019) Arzu Kalemci, R.
This study examines what fundamental issues are addressed in the tourism literature for defining sustainable development. By adopting a descriptive approach with a content analysis, 221 articles with the keywords “sustainable development” in their titles are analyzed in the current study. This study argues that although developmental and environmental dynamics is crucial, however, organizational dynamics of sustainable development should also be emphasized in the tourism literature. This study also shows that sustainability for companies operating in the tourism sector has a legitimating effect both at the organizational level and within the organization. © 2020 selection and editorial matter, Ipek Kalemci Tüzün, Mehmet Ergül and Colin Johnson; individual chapters, the contributors.

Copyright Protection by Robust Digital Image Watermarking in Unsecured Communication Channels
(Institute of Advanced Engineering and Science, 2017) Alasafi, L.; Göksu, T.; Albayati, A.
The transition from analog technologies to digital technologies has increased the ever-growing concern for protection and authentication of digital content and data. Owners of digital content of any type are seeking and exploring new technologies for the protection of copyrighted multimedia content. Multimedia protection has become an issue in recent years, and to deal with this issue, researchers are continuously searching for and exploring new effective and efficient technologies. This thesis study has been prepared in order to increase the invisibility and durability of invisible watermarking by using the multilayer Discrete Wavelet Transform (DWT) in the frequency plane and embedding two marks into an image for the purpose of authentication and copyright when digital content travels through an unsecured channel. A novel watermarking algorithm has been proposed based on five active positions and on using two marks. In addition to the extraction process, watermarking images will be subjected to a set of attack tests. The evaluation criteria have been the bases of assessing the value of SNR, PNSR, MAE and RMSE for both the watermarking images and the watermarking images after attacks, followed by the invisibility of the watermarking being measured before and after the attacks. Our lab results show high robustness and high quality images obtaining value for both SNR and PNSR. © 2017 Institute of Advanced Engineering and Science. All rights reserved.

The Crime of Genocide in International Law and Underlying Social Structures of the Crime: Rwanda Case
(Uluslararasi Iliskiler Konseyi dernegi, 2008) Coban, Ebru
Genocide is a crime which is defined under international law in the twentieth century and could not come about without the ideological, bureaucratic power of a modern state with its sanctions and modern discourses on identities and modern classifications. With a non-modern picture but with modem techniques of governing Rwanda was a place that genocidal killings occurred and is a place of a breaking case for modem theories. Rwanda has modern state characteristics in terms of monopoly of use of violence, giving orders and providing obedience of its people, surveillance, classification and registration of its people, and keeping discourses. Moreover, Rwandan culture that gives great importance to obedience and Rwandan geography that is so suitable to surveillance become additional factors. In that sense, Rwandan governments could influence to daily life of the people even to the smallest details of anyone. All factors provided a suitable base for the crime of genocide.
