The Causal Relationship Between Government Spending and Revenue: An Empirical Study from Greece

Abstract: This paper examines the relationship between government spending and revenues in Greece for the 1980–2015 period, using cointegration autoregressive distributed lag test (ARDL test) as well as causality test developed by Toda and Yamamoto. The results of cointegration of ARDL test showed that there is a cointegrated relationship between government spending and revenues. Also, causality test showed that there is a unidirectional causal relationship between spending and revenues in Greece with direction from government spending toward revenues.

The Meteorological Setting of a Particulate Air Pollution Episode During November 2009, in Western Macedonia Industrial Area, Greece

Abstract: A particulate air pollution episode of relatively long duration was recorded in the industrial basin of Western Macedonia, Greece, during November of 2009. A case study of the meteorological aspects of this episode is presented in this paper, based on the combined utilization of PM10 concentration measurements, surface and lower atmosphere parameters and simulations. An Omega blocking pattern which gradually transformed to a high-over-low pattern prevailed over central and southern Europe during the episode’s period. The absence of significant convection in the middle and lower troposphere combined with a weak horizontal wind field near the surface and the reduced mixing height, resulted in the pollutants’ trapping and the increased PM10 concentrations. The change of the synoptic setting marked the end of the episode.

Formal Methods in High-Level and System Synthesis

Abstract: The extreme complexity of today’s embedded systems and portable computing machines has motivated research in the area of high-level and system synthesis (HLS). HLS is the process of modeling the behavior of the system in a high, algorithmic level using a regular imperative programming language such as C or ADA, and automatically transforming this behavioral model into hardware implementations. If the HLS transformations that are applied on the source code are formal, then the generated system implementation is correct-by-construction. The HLS tasks include scheduling of operations, allocation and binding to library resources, and techniques for these tasks are explained here. This work surveys and reviews past research in the area of formal methods for high-level and system synthesis. Since this area of research has been active for almost three decades, first the early HLS attempts are reviewed and then the more mature toolsets and HLS algorithms are analyzed. A prototype HLS compiler tool that has been developed by the author is presented here which uses compiler-generators, RDF rules and logic programming in combination with XML validation interfaces for the internal state of the compiler. All these make the compilation process formal. The embedded scheduler PARCS and the formal compilation of the system are tested with a number of benchmarks and real-world applications.

Corporate Governance: A Comparative Analysis of the Accounts of the Telephone Companies Cosmote, Vodafone, and Wind

Abstract: The purpose of this paper is to present the structure governing corporate social responsibility in the mobile telecommunications sector in Greece. Because the sector is clearly oligopolistic and the competition in this type of the market is special, the corporate social responsibility plays a catalytic role in shaping the consumer perception of each company individually. Through this work the researchers hope to make clear the context of corporate social responsibility governing mobile companies in Greece.

Domestic vs. International E-Shopping: An Empirical Perceptions Analysis

Abstract: Contemporary commerce is completely different as regards features some years ago. Nowadays, a considerable number of individuals and firms take advantage of the information and communication technologies and conduct transactions online. In particular, the mobile industry along with the broad use of social networks and improvements in the internet bandwidth worldwide has created a completely different business environment. Consequently, the technology incited many consumers to cross-border e-shopping, allowing access to a wider variety of products and services, and in numerous circumstances, access to cheaper goods. The purpose of this chapter is to investigate the perceptions internet users have towards e-shops focusing on Greece. More precisely, it aims to find out whether there are contingent differences on customers' perceptions regarding domestic vs. international e-shops, since a gradually augmented number of people have been expressing their preference on non-domestic e-stores for their purchases. Additionally, the chapter intends to shed light on the difficulty in understanding vital aspects of e-consumer behaviour.
