    Construction of Integrals of Higher-Order Mappings

    Full text link
    We find that certain higher-order mappings arise as reductions of the integrable discrete A-type KP (AKP) and B-type KP (BKP) equations. We find conservation laws for the AKP and BKP equations, then we use these conservation laws to derive integrals of the associated reduced maps.Comment: appear to Journal of the Physical Society of Japa

    Turkish economic policy under AKP government: an assessment for 2002-2007

    Get PDF
    This article agrees with the received wisdom that the rule of AKP government has been associated with better macroeconomic outcomes in Turkey from 2002-2007. However, it argues that it is necessary to question the received wisdom for several reasons. First, AKP government’s contribution to Turkey’s economic performance from 2002-2007 was largely due to its consent to ‘tie its hands’ under the pre-existing International Monetary Fund (IMF) and European Union (EU) accession conditionality rather than because of AKP-specific policy innovation. Secondly, AKP’s attempt at policy innovation after 2004 have been associated with less impressive economic outcomes. Finally, the AKP has been unsuccessful in addressing the structural constraints and vulnerabilities that threaten the long-run sustainability of Turkey’s economic growth and its macroeconomic stability.Economic policy analysis; economic governance; inflation targeting; structural reforms; Turkish economy

    Justice and development party at the Helm: resurgence of islam or restitution of right of center predominant party?

    Get PDF
    General elections of July 22, 2007 witnessed a very rare occasion in Turkish politics. The Justice and Development Party (AKP), which had been in government since the 2002 elections managed to increase its votes dramatically and obtain an overwhelming majority in the Turkish Grand National Assembly (TGNA). It was a first since the 1954 elections in the country. The leader and the front bench of the AKP have come from the political Islamist National Outlook (Milli Gorus) movement. With immaculate Islamist credentials the electoral victories of the AKP in the 2000s have been interpreted as the demise of secularism and resurgence of Islam in Turkey. Has 47 percent of the Turkish electorate voted for political Islam in the July 22, 2007 elections? Is it religious credentials of the AKP or its leader and the front bench that have attracted the voters in droves to the support of that party at the polls, or are there some other factors at play? This paper sets out to examine and compare the voter profiles in the 2002 and 2007 elections, with the objective of determining the profiles of the voters who supported the AKP versus its main opposition Republican People’s Party (CHP), the champion of secularism in Turkish politics. The paper sets out to ascertain whether the voter profiles of the Turkish parties have changed between 2002 and 2007, and how? The nationally representative election surveys of 2002 and 2007 will be used to analyze such individual level characteristics of attitudes, beliefs and values of the Turkish voters, and assess the role played by religiosity, economic expectations and the performance of the economy, foreign policy, and in specific EU – Turkey relations, parochialism, and nationalist feelings in determining the preferences of the voters across the left – right spectrum in Turkey. Such an analysis will enable us to unearth the importance of religiosity in the voters’ choices, and the extent to which Turkish voters have shunned away from secularism per se

    Could Turkey’s new parties change the political balance? EPC Policy Brief 13 March 2020

    Get PDF
    New political trends are unfolding in Turkey. Recently established political parties have raised hopes for change in the country, impacting the political balance between the government and the opposition. While this is not a foregone conclusion, it is a development worth watching closely, including for the EU. The Justice and Development Party (AKP) has dominated Turkish politics for over 17 years. Nevertheless, with mounting domestic headaches and a moribund economy, the AKP seems to be running out of steam. Support for the party is at an all-time low, while President Recep Tayyip Erdoğan’s popularity is also in decline

    Party identification, islam and secularism in Turkey

    The current Turkish party system is only a few decades old, and some parties are even younger. We should expect scant evidence of psychological ties of the voters and the political parties they support at the polls in Turkey. Indeed, earlier research on the Turkish parties and voting behavior, conducted by Hofferbert and Erguder (1985), Kalaycioglu (1994 and 1999), Ozbudun (2000), Sayari and Esmer (2002), Carkoglu (2004), and Carkoglu and Hinich (2005) indicated that Turkey tends to host a plenitude of political parties due to several cultural and ideological divides that separate the Turkish party systems in various blocs. The above-mentioned literature indicates that secular – Islamist divide is in part responsible in the socio-cultural cleavages that divide up the Turkish body politic. Moreover, data analysis seems to indicate that the management of macro economy and performance of the parties in government influence electoral choices, and the socio-cultural cleavages of the country play relatively large role in determining party preferences of the voters in Turkey. However, the earlier research has been inconclusive about the role played by such psychological factors as party identification in Turkey. In this paper first of all, the role that such socio-cultural cleavages as secularism versus Islamism in determining party identification play is examined. Secondly various determinants of party preferences are comparatively examined to evaluate the role played by such factors as ideology, identity, economic expectations and party identification of the voters in Turkish politics of the early 2000s. A causal model that assesses the relative influence that ideological, economic, and psychological (party identification) factors play in the determination of party preferences of the Turkish voters is developed and tested by the help of the data collected by means of a national survey in April – May 2006. In the final and the third part of the paper a comparative evaluation of factors that explain party preferences across secular and Islamist parties in Turkey are attempted, with the specific aim of ascertaining the role that reason versus dogma play in the party politics that operate in a Muslim society and secular democratic syste

    Foreign policy orientation of Turkey's pro-Islamist parties: A comparative study of the AKP and Refah

    Get PDF
    This study aims to discuss the foreign policies of the pro-Islamist parties in Turkey by comparing the party programs and policies of the Justice and Development Party (Adalet ve Kalkınma Partisi) and the Welfare Party (Refah Partisi). By focusing on programs and policies separately, it is argued that pro-Islamist elements in the establishment and program of the parties do not necessarily translate to actual policies, particularly in foreign affairs. Moreover, pro-Islamist political parties are not monolithic in terms of member composition; the parties also differ from each other. Finally, the parties might have different policies in the domestic context while employing a more pragmatic and traditionalist perspective in terms of foreign policy

    Attitudinal orientation to party organizations in Turkey in the 2000s

    The Turkish party system experienced a serious blow in the early 1980s, when the military government in power closed down all the former legal political parties. Therefore, little evidence of strong psychological ties between voters and the political parties they supported at the polls is expected. This essay draws upon existing literature on voting behavior to develop four hypotheses to explain partisan affiliations of Turkish voters. Each of the hypotheses is then put to empirical tests, using data collected by means of a nationally representative survey. The four independent variables used in the four hypotheses are the role of parents' party identification (socialization), ideological orientations, economic expectations, and the ethnic identities of voters. Socialization emerges as a major determinant of partisan affiliation with the relatively older Republican People's Party (CHP) and Nationalist Action Party (MHP), while identifiers with the governing Justice and Development Party (AKP) take few cues from their parents and pay more attention to the economic performance of that party in government. Ideology seems to play a major role in determining the psychological orientations of those who feel attached to the CHP versus the AKP or the MHP but little role in differentiating AKP from MHP voters. Ethnicity only plays a role in partisan affiliation with the MHP

    The Accelerated Kepler Problem

    Full text link
    The accelerated Kepler problem is obtained by adding a constant acceleration to the classical two-body Kepler problem. This setting models the dynamics of a jet-sustaining accretion disk and its content of forming planets as the disk loses linear momentum through the asymmetric jet-counterjet system it powers. The dynamics of the accelerated Kepler problem is analyzed using physical as well as parabolic coordinates. The latter naturally separate the problem's Hamiltonian into two unidimensional Hamiltonians. In particular, we identify the origin of the secular resonance in the accelerated Kepler problem and determine analytically the radius of stability boundary of initially circular orbits that are of particular interest to the problem of radial migration in binary systems as well as to the truncation of accretion disks through stellar jet acceleration.Comment: 16 pages, 9 figures, in press at Celestial Mechanics and Dynamical Astronom
