A Methodology for Ontology-based Knowledge-level Inoperability among Parliaments
Most of the information systems (IS) interoperability research and practice in the e-government area has been focused on the operational level, aiming mainly at enabling the delivery of integrated electronic services involving several government agencies to citizens and enterprises based on the ‘one-stop shop’ model, and the support of co-operation among government agencies from the same or even different countries at the operational level. This paper is dealing with knowledge-level interoperability, which aims at the support of higher knowledge-intensive tasks of government, such as the formulation of legislation. In particular, it presents an ontology-based methodology for achieving knowledge-level interoperability among IS of Parliaments. It is based on the common use by Parliaments of the ontology of the ‘Issue-Based Information Systems’ (IBIS) framework for codifying the public policy related knowledge produced in the various stages of legislation formulation. Also, an application of the proposed methodology is presented for the case of the Law concerning ‘Contracts of Voluntary Cohabitation’ that has been recently passed by the Greek Parliament; its evaluation resulted in a proposal for a refinement of the above ontology that can be used for achieving a better codification of the knowledge that the main content (articles) of Laws contains
Transfer of technology and knowledge - The story of an enterprise system implementation
This paper aims at investigating empirically at the firm level the effect of the use of modern information and
communication technologies (ICT), and also of two other factors, the adoption of new forms of workplace
organization (which is regarded as a ‘complement’ of ICT), and trade (export) activities (a major characteristic
of modern economy), on the demand for employees’ (vocational) education and skills. The study is based on
firm-level data collected through a common questionnaire from firms’ samples of similar composition
(concerning firm sizes and industries) in Greece and Switzerland; from these data econometric models of similar
specification have been constructed for both countries. The results of multivariate analysis show that the
intensive use of ICT correlates positively with the employment shares of high-educated personnel and negatively
with the ones of the low-educated personnel. These findings are consistent with the hypothesis of ‘skill-biased
technical change’. Further, the intensive use of “employee voice”-oriented organizational practices correlates
positively with the employment shares of high-educated employees in both countries, and also negatively with
the employment share of low-educated ones only for the Swiss firms. The results for the “work design”
organizational practices are more ambiguous. Thus, there is only partial confirmation of the hypothesis of
skilled-biased organizational change. Finally, we found some evidence in favour of the trade effect (export
activities) only for the Swiss firms. Our results show both similarities and differences in the above aspects
between Greece and Switzerland, and indicate that national context characteristics affect the relationship of the
demand for employees’ (vocational) education and skills with ICT use, adoption of new forms of workplace
organization and trade
A Value Flow Model for the Evaluation of an E-Learning Service
Information Systems (IS) evaluation has been one of the most important and widely researched topics for more than two decades. Τhe evaluation of e-Learning is of critical importance in order to maximize the benefits from the huge investments made in this area. In this paper is presented a method for e-learning multi-layer evaluation and value flow model estimation. It includes evaluation of e-learning using three layers of value measures (efficiency measures, effectiveness measures, and intended future behaviour measures), and also the estimation of the relations between them. In this way a model of value generation and flow is developed. This method generates rich and useful information concerning the different types of value that e-learning creates, the mechanisms of their creation and also possible interventions for increasing them. A first application of this method is presented for the evaluation of an e-learning servic
Mediated behavioural change in human-machine networks: exploring network characteristics, trust and motivation
Human-machine networks pervade much of contemporary life. Network change is
the product of structural modifications along with differences in participant
be-havior. If we assume that behavioural change in a human-machine network is
the result of changing the attitudes of participants in the network, then the
question arises whether network structure can affect participant attitude.
Taking citizen par-ticipation as an example, engagement with relevant
stakeholders reveals trust and motivation to be the major objectives for the
network. Using a typology to de-scribe network state based on multiple
characteristic or dimensions, we can pre-dict possible behavioural outcomes in
the network. However, this has to be medi-ated via attitude change. Motivation
for the citizen participation network can only increase in line with enhanced
trust. The focus for changing network dynamics, therefore, shifts to the
dimensional changes needed to encourage increased trust. It turns out that the
coordinated manipulation of multiple dimensions is needed to bring about the
desired shift in attitude.Comment: Paper submitted to SocInfo, organised by the Oxford Internet

A conceptual framework for the adoption of big data analytics by e-commerce startups: a case-based approach
E-commerce start-ups have ventured into emerging economies and are growing at a significantly faster pace. Big data has acted like a catalyst in their growth story. Big data analytics (BDA) has attracted e-commerce firms to invest in the tools and gain cutting edge over their competitors. The process of adoption of these BDA tools by e-commerce start-ups has been an area of interest as successful adoption would lead to better results. The present study aims to develop an interpretive structural model (ISM) which would act as a framework for efficient implementation of BDA. The study uses hybrid multi criteria decision making processes to develop the framework and test the same using a real-life case study. Systematic review of literature and discussion with experts resulted in exploring 11 enablers of adoption of BDA tools. Primary data collection was done from industry experts to develop an ISM framework and fuzzy MICMAC analysis is used to categorize the enablers of the adoption process. The framework is then tested by using a case study. Thematic clustering is performed to develop a simple ISM framework followed by fuzzy analytical network process (ANP) to discuss the association and ranking of enablers. The results indicate that access to relevant data forms the base of the framework and would act as the strongest enabler in the adoption process while the company rates technical skillset of employees as the most important enabler. It was also found that there is a positive correlation between the ranking of enablers emerging out of ISM and ANP. The framework helps in simplifying the strategies any e-commerce company would follow to adopt BDA in future. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature
