A review of cyber security risk assessment methods for SCADA systems

This paper reviews the state of the art in cyber security risk assessment of Supervisory Control and Data Acquisition (SCADA) systems. We select and in-detail examine twenty-four risk assessment methods developed for or applied in the context of a SCADA system. We describe the essence of the methods and then analyse them in terms of aim; application domain; the stages of risk management addressed; key risk management concepts covered; impact measurement; sources of probabilistic data; evaluation and tool support. Based on the analysis, we suggest an intuitive scheme for the categorisation of cyber security risk assessment methods for SCADA systems. We also outline five research challenges facing the domain and point out the approaches that might be taken

When Socialization Goes Wrong: Understanding the We-Intention to Participate in Collective Trolling in Virtual Communities

Although collective trolling poses a growing threat to both individuals and virtual community owners, the information systems (IS) literature lacks a rich theorization of this phenomenon. To address the research gaps, we introduce the concept of we-intention to capture the collective nature of collective trolling in virtual communities. We also integrate the social identity model of deindividuation effects (SIDE) and situational action theory to invoke the sociotechnical perspective in theorizing collective trolling in virtual communities. The objective of this study is to use the sociotechnical perspective to understand the we-intention to participate in collective trolling in virtual communities. We test our proposed model using data gathered from 377 Reddit users. Our moderated mediation analysis elaborates how technical elements (i.e., anonymity of self and anonymity of others) influence the we-intention to participate in collective trolling via individual-based social elements (i.e., perceived online disinhibition and social identity), with an environment-based social element (i.e., the absence of capable guardianship) as a boundary condition. We contribute to research by explaining collective trolling in virtual communities from the group-referent intentional action perspective and sociotechnical perspective. We also offer practical insights into ways to combat collective trolling in virtual communities

An evaluation of cultural integration and the malleability of socio-cultural constructs in global organizations

This study responds to calls for pragmatic context-driven scholarship to evaluate the perceived need for cultural integration in global organizations. This paper aims to fill the gap between theoretical frameworks and contemporary phenomena with a grounded theory, quantitative ethnography study designed to explore the perceived need for cultural integration to improve business outcomes in global organizations, while also evaluating the perceived need for a dedicated framework to develop cultural integration to shift socio-cultural epistemic frames in global teams. Data were collected through semi-structured interviews conducted with 18 global executives, while 173 surveys were completed by global team members. Analysis of the dataset was done through thematic content analysis and epistemic network analysis. The research demonstrated that cultural integration, and its associated constructs, were perceived as critical to group and organizational success. Global executives and leaders confirmed the need for a dedicated framework for cultural integration to improve business outcomes. The current study addressed four research questions: To what extent is there a perceived need for Cultural integration in global organizations? To what extent is Cultural integration perceived relevant to business outcomes in global organizations? To what extent do leaders perceive socio-cultural epistemic frames are malleable at the group level? To what extent is there a perceived need for a dedicated framework to develop Cultural integration to shift socio-cultural epistemic frames in global teams? This empirical study confirms that socio-cultural epistemic frames are malleable at the group level to develop cultural integration and that there is a perceived need for a dedicated framework to develop cultural integration for improved business outcomes in global organizations

Non-Equilibrium Social Science and Policy

The overall aim of this book, an outcome of the European FP7 FET Open NESS project, is to contribute to the ongoing effort to put the quantitative social sciences on a proper footing for the 21st century. A key focus is economics, and its implications on policy making, where the still dominant traditional approach increasingly struggles to capture the economic realities we observe in the world today - with vested interests getting too often in the way of real advances. Insights into behavioral economics and modern computing techniques have made possible both the integration of larger information sets and the exploration of disequilibrium behavior. The domain-based chapters of this work illustrate how economic theory is the only branch of social sciences which still holds to its old paradigm of an equilibrium science - an assumption that has already been relaxed in all related fields of research in the light of recent advances in complex and dynamical systems theory and related data mining. The other chapters give various takes on policy and decision making in this context. Written in nontechnical style throughout, with a mix of tutorial and essay-like contributions, this book will benefit all researchers, scientists, professionals and practitioners interested in learning about the 'thinking in complexity' to understand how socio-economic systems really work

The structure and dynamics of multilayer networks

In the past years, network theory has successfully characterized the interaction among the constituents of a variety of complex systems, ranging from biological to technological, and social systems. However, up until recently, attention was almost exclusively given to networks in which all components were treated on equivalent footing, while neglecting all the extra information about the temporal- or context-related properties of the interactions under study. Only in the last years, taking advantage of the enhanced resolution in real data sets, network scientists have directed their interest to the multiplex character of real-world systems, and explicitly considered the time-varying and multilayer nature of networks. We offer here a comprehensive review on both structural and dynamical organization of graphs made of diverse relationships (layers) between its constituents, and cover several relevant issues, from a full redefinition of the basic structural measures, to understanding how the multilayer nature of the network affects processes and dynamics.Comment: In Press, Accepted Manuscript, Physics Reports 201
