Athanasios Mazarakis studied Psychology with minor subject business administration at the University of Mannheim. Main focus of his studies were on statistical methods and evaluations, organizational psychology, multimedia learning and cognitive psychology. In his diploma thesis he worked on the Cognitive Load Theory and split-attention effect. Also he worked as online-mediator internship at the University of Utrecht.
 
Since January 2009 he is working in the department Information Process Engineering at FZI. The main research topic is the development, analysis and assessment of Web 2.0 instruments to conquer cognitive, social and motivational barriers at organisations.

Organisational Learning from the Perspective of Knowledge Maturing Activities
IEEE Transactions on Learning Technologies, vol. , no. 3, 2013, pp.

Abstract The level of similarity of knowledge work across occupations and industries allows for the design of supportive information and communication technology (ICT) that can be widely used. In a previous ethnographically-informed study, we identified activities that can be supported to increase knowledge maturing, conceptualized as goal-oriented learning on a collective level. The aim of this paper is to investigate the current state of support and success of these knowledge maturing activities and to contrast them with their perceived importance, in order to identify those which have the highest potential for being supported by ICT. Quantitative and qualitative data were collected through telephone interviews with representatives from 126 organizations throughout Europe in a sample stratified according to size, sector and knowledge-intensity. The activities that appear to be most promising are ‘reflecting on and refining work practices and processes’, ‘finding people with particular knowledge or expertise’, as well as ‘assessing, verifying and rating information’. Rich empirical material about how these activities are performed and also the issues that emerged and need to be managed were collected. Three clusters of organizations were identified: best performing organizations, people- and awareness-oriented organizations and hesitant formalists. It was found that a balanced knowledge strategy that leaned towards personalization outperformed a codification strategy.

Culture Awareness for Supporting Knowledge Maturing in Organizations
In: Motivation und kulturelle Barrieren bei der Wissensteilung im Enterprise 2.0, Workshop auf der Mensch & Computer 2011, 2011

Abstract The success and sustainability of informal learning support at the workplace largely depends on motivational, social, and cultural aspects of the involved individuals, teams, and organizations. In this paper, we present our empirical findings from a large-scale interview-based study on those aspects with respect to knowledge development in companies. We draw some conclusions that influence the development of future culturally aware systems for the enterprise and organizations.

Feedback in Social Semantic Applications
International Journal of Knowledge Engineering and Data Mining (IJKEDM), vol. , no. , 2011, pp.

Abstract This article examines the role of feedback mechanisms in social semantic web applications. It introduces different social semantic applications and the function that system feedback can play in these, although only a small portion of possible roles of feedback in such applications is addressed by the state of the art. The authors present an approach with four concrete feedback mechanisms and an experiment on the use of explicit feedback to foster user contribution and motivation. Finally the article details the large number of open research questions in this area.

Knowledge Maturing Activities and Practices Fostering Organisational Learning: Results of an Empirical Study
In: Sustaining TEL: From Innovation to Learning and Practice 5th European Conference on Technology Enhanced Learning, EC-TEL 2010, Barcelona, Spain, September 28 - October 1, 2010. Proceedings, Lecture Notes in Computer Science vol. 6383, Springer, 2010, pp. 151-166

Abstract Knowledge work is performed in all occupations and across all industries. The level of similarity of knowledge work allows for designing supporting tools that can be widely used. In this paper an activity-based perspective towards knowledge work is taken. Based on findings from a previous ethnographically-informed study, we identified valuable activities to be supported in order to increase knowledge maturing inside companies. The goal of this paper is to contribute to which knowledge maturing activities are deemed important, so that they can be supported by IT services. Quantitative and qualitative data have been collected in 126 organisations of different size, sector and knowledge intensity. Important feedback and issues emerged and need to be managed in order to support success in the knowledge maturing activities that allow improvement of organisational learning through the dissemination and application of the most appropriate knowledge.
