The exact contribution of corporate social responsibility (CSR) to a company as well as to its stakeholders should be measurable in order to be evaluated correctly. The difficult task of measuring the results of CSR has been a matter of significant research both by academics and by practitioners. Some of the literature on corporate social responsibility combines CSR with stakeholder theory introducing corporate social performance. The literature has attempted to describe emerging models of the issues that lead to a coherent model of what would represent corporate social performance. However, it is the case that social aspects are "soft" in nature, therefore being difficult to quantify. Innovated methods of performance measurement such as that of Balanced Scorecard has lately been introduced in some companies in their attempt to include nonfinancial indicators to give a more balanced and forecasting power to the traditional financial performance assessment system, but the view of corporate social responsibility is rarely taken into account. Furthermore, management frameworks that try to cover social and environmental aspects, such as Global Reporting Initiative, by providing a number of related performance measures, are not able to connect them with corporate strategy and are poor evaluators of cause-effect relationships. In the present paper, a CSR performance measurement framework based on the adoption of the Balanced Scorecard approach is presented. For the development of the proposed framework, the existing assessment of CSR and Corporate Sustainability actions of the Greek companies of different sectors was analysed in order to identify common practices in CSR performance evaluation as well as existing limitations. Taking into account the social indicators suggested by the traditional balanced scorecard views, an extension of its structure is proposed in order to better embody the environmental and social aspects of company performance.

Purpose -The purpose of this paper is to describe and analyze the benefits of the application of a requirements engineering framework to assist Enterprise Resource Planning (ERP) development. This framework combines the technology-driven and the process-driven approaches for requirements analysis and implementation. Specific business process modeling methods enhance the framework and assist the formulation of the functional specifications of the ERP system and the management of requirements. Design/methodology/approach -A case study strategy was chosen as the most appropriate method to answer the research question and test the theoretical propositions. The case study's unit of analysis is a Greek manufacturing company and its ERP implementation project. A requirements engineering framework enhanced with business process modeling methods was applied and the results were evaluated using metrics for ERP implementation success. Data were collected using multiple sources of evidences, including interviews with various stakeholders, structured questionnaires, direct observations, vendors' functionality papers and company's documentation.Findings -This study proves that the configuration of ERP's reference models together with the adjustments of organization's processes, provided through a structured requirements engineering framework can lead to reliable functional specifications, a smooth transition to an ERP system and, eventually, to successful ERP implementation, concerning its alignment with requirements. Research limitations/implications -A single case study is conducted in a typical manufacturing company, providing opportunities for further research in other industries, testing in parallel well-defined requirements and other success factors for ERP implementation. Originality/value -The paper fulfils the identified needs for applied methodologies and frameworks for requirements engineering which can assist successful ERP implementations.

Efficient integration and visualization of heterogeneous biomedical information in a single view is a key challenge. In this study, we present Arena3D web , the first, fully interactive and dependency-free, web application which allows the visualization of multilayered graphs in 3D space. With Arena3D web , users can integrate multiple networks in a single view along with their intra- and inter-layer connections. For clearer and more informative views, users can choose between a plethora of layout algorithms and apply them on a set of selected layers either individually or in combination. Users can align networks and highlight node topological features, whereas each layer as well as the whole scene can be translated, rotated and scaled in 3D space. User-selected edge colors can be used to highlight important paths, while node positioning, coloring and resizing can be adjusted on-the-fly. In its current version, Arena3D web supports weighted and unweighted undirected graphs and is written in R, Shiny and JavaScript. We demonstrate the functionality of Arena3D web using two different use-case scenarios; one regarding drug repurposing for SARS-CoV-2 and one related to GPCR signaling pathways implicated in melanoma. Arena3D web is available at http://bib.fleming.gr:3838/Arena3D or http://bib.fleming.gr/Arena3D .

Purpose This paper aims to construct an assessment framework to establish a maturity model for Web Electronic Services offered at a local government level and investigate the maturity of Greek municipalities in the E-Government field, trying to correlate how this is affected by demographic variables. Design/methodology/approach An original assessment framework regarding municipal Electronic Services was created based on the literature review. The assessment framework was included in a methodological approach supported by the PROMETHEE II method, as well as by selected statistical methods. The framework and the methodological approach were applied in the case of Greek municipalities. Findings The analysis revealed the low maturity level of Greek municipalities in Electronic Services sector. The Greek case study indicated that the proposed framework and methodological approach could provide useful insights to municipalities for the improvement of its E-Government Web services based on their strategic preferences. Research limitations/implications The assessment took place only in Greece, assessing all the country's municipalities and conducting research only in the municipalities’ websites. The proposed methodology suggests that the PROMETHEE II multi-criteria decision analysis method can support the assessment of the maturity level of local government entities. Moreover, the combination of the PROMETHEE II–empowered assessment framework with demographic statistical analysis can assist orthological decision-making concerning future investments in Web Electronic Services. The methodology could be a good option for future research efforts (assessments) in municipalities, in Greece and worldwide. Practical implications The framework is both easy to use and fairly complete. The fact that the assessment was conducted in all the Greek municipalities makes it much more reliable, as it provides the whole picture. The suggested methodology which includes the proposed framework could be used in the cases of municipalities in other countries to assist future actions concerning the investment in Web Electronic Services. Originality/value This study provided a medium-size framework, being both complete and easy to use during the evaluation process of all the municipalities in Greece. In addition, the statistical analysis received data from a decision-making tool to execute the clustering (Cluster analysis is usually performed based on the raw data).

Purpose The purpose of this paper is to review of the literature about lean six sigma (LSS) implementation in European organizations written by academics or practitioners from European institutions to extract useful conclusions about LSS adoption in European companies and to suggest direction for future research concerning the broader LSS application in them. Design/methodology/approach This study has been conducted by reviewing 58 papers, found in top journals, coming from European institutions that present studies of European companies and fulfill the selected inclusion criteria. Findings The analysis of the literature revealed the level of penetration of the LSS methodology in organizations of each European country. The study of the papers revealed the sectors and the size of companies that are more active in LSS application, the method used in each project, the tools which are deployed and the interconnection between LSS and other topics through the project implementation. Research limitations/implications The limited access provided by the authors’ institution only to three major publishers (Emerald, Elsevier, Taylor and Francis) and the focus of the search only in European organizations were the main limitations of this review. Practical implications This paper provides both academics and practitioners with valuable insights about LSS implementation in European organizations, presenting a complete analysis framework of the literature and highlighting gaps for further research. Originality/value An extended and detailed analysis of LSS adoption in Europe has not been conducted before. This review presents a clear view about how LSS projects in European organization have been applied so far and suggests ways of how the literature could be enriched to facilitate the LSS implementation.
