TL;DR: In this paper, the energy eigenvalues of the Schrodinger equation were derived by modification of the first and second order Yoshida symplectic methods, and numerical results were obtained for the one-dimensional harmonic oscillator and Morse potential.
Abstract: The computation of the energy eigenvalues of the one-dimensional time-independent Schrodinger equation is considered. Exponentially fitted and trigonometrically fitted symplectic integrators are obtained, by modification of the first and second order Yoshida symplectic methods. Numerical results are obtained for the one-dimensional harmonic oscillator and Morse potential.

TL;DR: In this article, the Schrodinger equation is considered by partial discretization and the discretized problem is treated as an ordinary differential equation problem and Numerov type methods are used to solve it.
Abstract: The solution of the two-dimensional time-independent Schrodinger equation is considered by partial discretization. The discretized problem is treated as an ordinary differential equation problem and Numerov type methods are used to solve it. Specifically the classical Numerov method, the exponentially and trigonometrically fitting modified Numerov methods of Vanden Berghe et al. [Int. J. Comp. Math 32 (1990) 233–242], and the minimum phase-lag method of Rao et al. [Int. J. Comp. Math 37 (1990) 63–77] are applied to this problem. All methods are applied for the computation of the eigenvalues of the two-dimensional harmonic oscillator and the two-dimensional Henon–Heils potential. The results are compared with the results produced by full discterization.

TL;DR: In this paper, the solution of the one-dimensional time-independent Schrodinger equation is considered by trigonometrically and exponentially fitted symplectic integrators, and numerical results are obtained for the one dimensional harmonic oscillator and the exponential potential.
Abstract: The solution of the one-dimensional time-independent Schrodinger equation is considered by trigonometrically and exponentially fitted symplectic integrators. The Schrodinger equation is first transformed into a Hamiltonian canonical equation. Numerical results are obtained for the one-dimensional harmonic oscillator and the exponential potential.

TL;DR: In this article, the authors investigated the use of the Web by candidates during their campaign in the Greek local municipal elections of 2002 and found that the overwhelming majority of candidates have not used the Web as a basic information provision medium and has not explored the interactivity features for increasing levels of awareness by the voters.
Abstract: This study attempts to investigate the Web use by candidates during their campaign in the Greek local municipal elections of 2002. Municipal elections take place simultaneously with prefecture elections to decide local officials in 900 municipalities of the 51 prefectures. The municipal and prefecture electoral contests of 2002 were the first attempts of candidates to include the Web into their campaign strategies. The focus of the study is on how many candidates were going online, how much interactivity was used, what kind of information was distributed, and what kinds of multimedia tools were present. The study indicates that the overwhelming majority of municipal candidates has not used the Web as a basic information provision medium and has not explored the interactivity features for increasing levels of awareness by the voters. Comparing candidates with a Web campaign strategy to those without, we identified that candidates with a Web strategy won the contest in most of the cases. This study...

TL;DR: In this paper, the numerical integration of Hamiltonian systems by symplectic modified partitioned Runge-Kutta methods with the trigonometrically fitted property is considered, and a new method of second-order Runge Kutta method with trigonometric fitting is proposed.
Abstract: The numerical integration of Hamiltonian systems by symplectic modified partitioned Runge-Kutta methods with the trigonometrically fitted property is considered in this paper. We construct new symplectic modified Runge-Kutta method of second order with the trigonometrically fitted property. We apply our new method as well as other existing methods to the numerical integration of the harmonic oscillator, the two dimensional harmonic oscillator, the two-body problem and an orbit problem studied by Stiefel and Bettis.

TL;DR: In this paper, the authors present a survey of political marketing in Greece, focusing on the contribution of Greek scholars to the fast growing body of knowledge in this academic field, which has attracted the interest of marketers, political scientists and communication experts.
Abstract: What can be said about political marketing in Greece? This is the question that was addressed at a conference held in June 2003 at the Technological Educational Institution (TEI) of Western Macedonia in Kastoria, Greece. The conference initiated a dialogue among academics and practitioners/commentators as well as laid the foundation for the contribution of Greek scholars to the fast growing body of knowledge in this academic field. Political marketing has grown as a disciplined field of study in the past two decades, attracting the interest of marketers, political scientists and communication experts. To illustrate the growing academic interest suffice to point out the plethora of academic books that have been pub-

TL;DR: In this paper, a store image scale was constructed for fast food restaurants and a regression analysis and a structural equation analysis were performed to indicate the relative importance of each factor, which showed that intangible factors are more important than the tangibles for store image formation and for consumer satisfaction.
Abstract: Store image is made up of both tangible and intangible attributes. The knowledge of the composition is of great value for marketing managers and researchers. A store image scale was constructed for fast food restaurants. The scale contains three tangible and three intangible factors. Then a regression analysis and a structural equation analysis were performed to indicate the relative importance of each factor. Results showed that intangible factors are more important than the tangibles for store image formation and for consumer satisfaction. Researchers and marketing managers can use the instrument to have a better understanding of consumer behavior and improve marketing mix.

TL;DR: In this paper, a study was carried out in order to identify what affects unplanned behavior, which accounts for a significant amount of supermarket purchases, and the results found that consumers paid emphasis to specific attributes that, in turn, influenced their purchasing behavior, either planned or unplanned.
Abstract: This study is being carried out in order to identify what affects unplanned behaviour, which accounts for a significant amount of supermarket purchases. This should have a significant affect on the way products are marketed given that most purchasing decisions would appear to be made in the store itself. The empirical work combined qualitative and quantitative methods and the results found that consumers paid emphasis to specific attributes that, in turn, influence their purchasing behaviour, either planned or unplanned. The above will support retail managers during the development of store strategies with the ultimate aim to influence consumer behaviour towards increased product purchasing.
