Journalism in a state of flux: Journalists as agents of technology innovation and emerging news practices

Lia-Paschalia Spyridou; Maria Matsiola; Andreas Veglis; George Kalliris; Charalambos A. Dimoulas

The move to a networked media environment presents a range of challenges for journalistic roles, norms and daily practices. This article employs actor network theory to investigate how different actors negotiate and ultimately shape the manner in which the internet and related digital technologies are embedded in the newsroom. Findings suggest that professional culture – articulated in skills, ideas and practices – acts as a network that weakens the potential impact of technology towards innovation and audience-oriented models of journalism. The results point to the conclusion that the internet and related tools are seen as empowering journalists to do their (traditional) jobs better instead of moving on to the next stage built around a stronger commitment to capitalize on the growing sociotechnical potential.

Dependability evaluation of interconnection networks

Andreas Veglis; Andreas S. Pomportsis

Abstract A novel method aiming at evaluating dependability of multiprocessor systems is presented. The systems under evaluation can incorporate various interconnection systems namely crossbar, multiple-bus, single and multiple path multistage. The analysis can also be employed in the case of hierarchical multiprocessor systems.

Web Third-person effect in structural aspects of the information on media websites

Nikos Antonopoulos; Andreas Veglis; Antonis Gardikiotis; Rigas Kotsakis; George Kalliris

Sample from media websites, 9150 respondents, Greece.Factors that predict the Web Third-person effect (WTPE) were found.Age has statistically significant effects on WTPE. In this study, the characteristics of what users observe when visiting a media website as wells as the prediction of the impact on oneself, friends and others are researched. The influence that this information has over their opinion verifies the existence of Web Third-person effect (WTPE). With the use of an online survey (N=9150) in all media websites it was proved that the variables that have a greater impact either on others or our friends than ourselves are: The number of users being concurrently online on the same media website, the exact number of users having read each article on a media website as well as the number of users having shared a news article on facebook, twitter, or other social networks. Moreover, age is a significant factor that explains the findings and is important to the effect. Additionally, factors that affect the influence of the user generated messages on others than on oneself were found. Furthermore, the more credible the news is perceived to be and when there is not a particular mediated message the WTPE is absent confirming the existing theory.

Investigating Search Engine Optimization Factors in Media Websites

Dimitrios Giomelakis; Andreas Veglis

Rapidly evolving digital technologies across the last two decades have undeniably caused great changes in the field of journalism. The development of online journalism has affected the processes of journalistic work, creating at the same time new techniques and practices. On the internet, search engines still drive a great amount of traffic to news websites. For that reason, factors such as visibility and high ranking on search engines’ results pages remain crucially important for media organizations. Nowadays, journalists or Web editors should be able to write and create appropriate content for the Web. This paper discusses in detail the impact of Search Engine Optimization (SEO) on digital journalism. Through a quantitative analysis, a survey concerning Greek media websites is presented. The aim was twofold: on the one hand, to find out to what extent the use of SEO affects the traffic of a media website whilst, on the other hand, to discover to what degree media professionals in Greece utilize the possibilities given through search engines in order to increase traffic. Finally, a number of SEO elements and practices often used in news content are noted.

Journalists in the Age of ICTs: Work Demands and Educational Needs

Andreas Veglis; Andreas S. Pomportsis

This paper discusses in detail the issue of journalists’ usage of information and communication technologies (ICTs). More precisely, it proposes a model describing the information space available for journalists. It also describes thoroughly the necessary ICT skills that a journalist must possess to cope successfully with the work demands. A survey concerning ICT usage by professional journalists is also presented. The results of the survey indicate a lack of knowledge in certain areas of ICTs. The reasons behind this lack of ICT skills are discussed and a solution to this problem is proposed, which is based on continuing education programs that can foster the adoption of novel ICT tools and services by professional journalists.

Teaching performance evaluation of multiprocessor architectures with Mathcad and MathConnex

Andreas Veglis; C. A. Barbargires; Andreas S. Pombortsis

This paper presents the development of an interactive environment that facilitates the performance evaluation of multiprocessor architectures with Mathcad and MathConnex. This environment was primarily designed for utilization as an interactive computer laboratory exercise for teaching undergraduate students of the Computer Science Department at the Aristotle University of Thessaloniki, Greece.

Performability analysis of Clos multiprocessor systems

Andreas Veglis; Andreas S. Pombortsis

In this paper, we consider the problem of performability of a class of multistage interconnection networks, namely, the Clos network. Performability in the context of this paper is defined as a metric that combines measures like performance and availability of gracefully degradable fault-tolerant multiprocessor systems. The analysis includes nonuniform traffic patterns. Various configurations of Clos systems are studied. The results are compared and discussed.

Investigating quality of Experience and Learning (QoE & QoL) of audiovisual content broadcasting to learners over IP networks

George Kalliris; Charalampos Dimoulas; Andreas Veglis; Maria Matsiola

This paper investigates the implementation and validation of different qualities for live broadcasting of courses over the Internet. The main aim of this work is to identify the adequate balance between the required bandwidth for live broadcasting and the Quality of Experience and Learning (QoE & QoL). The data used in this study was acquired from real-world learning scenarios.

Modeling Cross Media Publishing

Andreas Veglis

The conversion of informatics with communication technologies in the last twenty five years has greatly affected the media industry. Thus the technology for the distribution of journalistic information in various forms has become more easily available. This paper attempts to model cross media publishing. More specific it describes the steps in deploying a successful cross media publishing that can help a newspaper organization to adapt to the continuously changing newspaper market.

Design of a Web based interactive computer lab course

Andreas Veglis

The Information Age has created many challenges for the traditional established educational institutions. This paper describes the design of World Wide Web-based computer laboratory courses. The purpose of this effort was to support a series of office automation courses and to prepare a series of distance learning courses. Also, the integration of the WWW (and of the Internet in general) in the teaching process is forcing students to familiarize themselves with the use of this valuable tool.
