A Reference Model and a Dedicated Method in Support of Cyber-Security by Design:A Reality Check
No full textThe electricity sector increasingly intertwines IT and the physical grid, increasing the risk of cyber attacks on this critical infrastructure. Hitherto, we have developed a modeling method to support cyber-security by design in the electricity sector by providing (1) a multi-level reference model, (2) a semi-automated security assessment, and (3) a dedicated process model. In this paper, we focus on four challenges identified based on interactions with domain experts, namely: (1) automated model creation; (2) accounting for changing security requirements; (3) multi-level model management; and (4) incentives for modelers. These challenges are relevant to our modeling method and overlap with challenges on the practical uptake of modeling in general.</p

Towards a Threat Modeling Language for Vessel Navigation and Port Call Optimization - harborLang
No full textThis paper presents harborLang, a novel threat modeling language tailored for the maritime sector, built on the Meta Attack Language (MAL) framework. harborLang addresses the unique security challenges in maritime transport by enabling modeling and mitigation of potential threats. Through integrating specific maritime domain knowledge, harborLang empowers stakeholders to construct comprehensive threat models, enhancing decision-making and operational safety in seaports and vessel navigation.</p
Towards ontological convergence of accounting frameworks
No full textConverging and matching frameworks, standards, and ontologies is crucial for achieving semantic interoperability, integration, and alignment of information across different systems and domains. The corporate reporting domain, like many others, is governed by a complex array of accounting, financial reporting, and sustainability standards. This paper presents a novel approach to addressing the convergence challenge between the IFRS and US GAAP Conceptual Frameworks for Financial Reporting by grounding them in UFO-based upper ontologies. A converged ontology is developed and modeled in OntoUML, with the resulting converged concepts defined and discusse
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Value-Based Security Requirements in a Highly Decentralized Digital Ecosystem:the MUSIC360 Case
No full textSecurity requirements in digital ecosystems should be first and foremost driven by the notion of economic value. Attackers are interested in objects of value, which are exchanged between actors in a network of organizations and end-users. We explain how we derive data-oriented security requirements by means of high level goals, a value model representing the ecosystem, and a data model detailing the value model. The approach is illustrated and validated in a complex ecosystem in the music sector.</p
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
