Combining efficiency and resilience assessments in industrial symbiosis value chains: a comprehensive flow analysis

The viability of firms that participate in industrial symbiosis (IS) is influenced by the impact that by-product synergies have on the economic efficiency and resilience of those firms in the IS network. Systems theory, industrial ecology, and value chain dynamics constitute the necessary frameworks to analyze the viability of IS value chains through efficiency and resilience assessments. Using Mexico’s Altamira Industrial Port as a case study, we identify and describe three IS value chains A, B and C and build variables to measure viability through efficiency and resilience. We find that only the three participating firms in value chain B are both sufficiently efficient and resilient to constitute viability. Moreover, these three firms (CABOT, INSA, and CHEMTURA) represent an anchor in port’s/network’s IS viability through the integration of a resilience and efficiency analysis by value chain. The study attempts to get an improved systemic understanding of IS value chain viability if resilience is aggregated to the efficiency analysis of by-product synergic exchanges of each firm involved in the IS. Finally, we recommend applying modular assessments on efficiency and resilience to firms participating in IS value chains, because according to the size and length of stressors influencing the IS dynamics, different actions should be implemented in the industrial ecosystem to anticipate potential scenarios where short-term, long-term, and structural stressors will endanger the viability of the IS network/value chainThis project has received funding from the KTU School of Economics and Business, grant holder of the European Research Area Grant – ERA chairs – “Industry 4.0 impact on management practices and economics” and the ERASMUS + Program of the European Union (Jean Monnet Excellence Center on Sustainability, ERASME) and CAP 20-25 AcademiaPostprint (author's final draft

An Optimized Dynamic Process Model of IS Security Governance Implementation

The year 2011 has witnessed a lot of high profiles data breaches despite the availability of IS security and governance controls, frameworks, standards and models for organisations to choose from; and the technical advances made in intrusion prevention and detection. Taking this issue into account the objective of this paper is to identify and analyse the weaknesses in the IS security defences of organisations from a holistic perspective, and propose a dynamic IS security governance process model for the implementation of appropriate controls and mechanisms for optimised IS security. Optimization is achieved through the strategic overlap of security and governance frameworks implemented in a prioritized phased manner for efficiency and effectiveness in cost, time and effort. The paper starts with the analysis of data breaches to identify the weaknesses in the organisational information system. This is followed by the analysis of recommended requirements and dimensions of effective IS security architecture, IS governance, concepts and models to identify relevant frameworks used in IS security and governance. Thereafter, the best practices for implementing the model is evaluated and finally the frameworks and IS entities are integrated into an optimized Information Systems Security and Governance (ISSG) process model

Youth A Multicriteria Approach for the Evaluation of the Sustainability of Re-use of Historic Buildings in Venice

The paper presents a multiple criteria model for the evaluation of the sustainability of projects for the economic re-use of historical buildings in Venice. The model utilises the relevant parameters for the appraisal of sustainability, aggregated into three macroindicators: intrinsic sustainability, context sustainability and economic-financial feasibility. The model has been calibrated by a panel of experts and tested on two reuse hypothesis of the Old Arsenal in Venice.multiple criteria valuation, economic reuse, historical building conservation

The Network-Firm as a Single Real Entity: Beyond the Aggregate of Distinct Legal Entities

This paper intends to depart from a critique of the nexus of contracts theory of the firm endowed with its moral personification to propose some theoretical foundations of the firm as a real entity. Some old legal views of the corporation are mobilized to complete the conceptual vacuity of economic theories. This provides crucial insights for modern complex organizations such as the network-firm. The integrating and unifying role of intra-network power relationships is then emphasized and some law and economics of the network-firm are ultimately proposed to clarify the argument that the network-firm − as the firm stricto sensu − is a singular real entity composed from distinct legal entities.Law and economics, contract theory of the firm, network-firm, legal fiction, real entity

A Multi-faceted Approach to Collaborative Health Information Systems

Modern healthcare is confronted with increasing costs and complexity, progressive population ageing and pandemics triggered by new disease strains and population displacements fuelled by conflicts and climate change. In this context, effective cooperation and interoperability of the participants and their information systems in the healthcare effort becomes paramount. This brings about significant challenges, as healthcare institutions are typically hierarchical and heterogeneous owing to a complex administrative, geographical and historical context. At the same time, governments find it increasingly difficult to rely on ‘silo’ type information and organisational paradigms in order to manage population wellbeing. Thus, there is an increasing need for innovative, holistic and integrated models that take into account all essential aspects, elements and especially life cycles of all the healthcare effort participants. Building on previous research and applications, this paper proposes that the required modelling artefacts can be built using a life cycle-based holistic paradigm enabled by advances in Information Systems, Interoperability, Collaborative Networks and Enterprise Architecture. This multi-faceted approach holds the promise to a sound platform for sustainable solutions to both long and short-term challenges to population health and well-being
