A virtual testbed for analysis and design of sensorimotoric aspects of agent control
1997
Abstract In this paper XRaptor is introduced, an object-oriented simulation tool. It provides a virtual multi-agent world which acts as testbed for agent control mechanisms. This environment encompasses a 3-dimensional space, in which the agents may move. Currently agents are realized modelling some abstract properties of flies and bats. XRaptor provides different levels of information flow and world manipulation capabilities from the agents' point of view. A further purpose of XRaptor is educational: Different teams of developers may design control units for agents which can then be subjected to a tournament.
ERP systems in SMEs: A literature review
2011
Published version of a chapter in Proceedings of the 44th Hawaii International Conference on System Sciences. Also available from the publisher: http://doi.dx.org/10.1109/HICSS.2011.191 This review summarizes research on enterprise resource planning (ERP) systems in small and medium-size enterprises (SMEs). Due to the close-to-saturation of ERP adoptions in large enterprises (LEs), ERP vendors now focus more on SMEs. Moreover, because of globalization, partnerships, value networks, and the huge information flow across and within SMEs nowadays, more and more SMEs are adopting ERP systems. Risks of adoption rely on the fact that SMEs have limited resources and specific characteristics that ma…
European Banking Union and bank risk disclosure: the effects of the Single Supervisory Mechanism
2022
AbstractThis paper provides evidence on the impact of European Banking Union (BU) and the associated Single Supervisory Mechanism (SSM) on the risk disclosure practices of European banks. The onset of BU and the associated rules are considered as an exogenous shock that provides the setting for a natural experiment to analyze the effects of the new supervisory arrangements on bank risk disclosure practices. A Difference-in-Differences approach is adopted, building evidence from the disclosure practices of systemically important banks supervised by the European Central Bank (ECB) and other banks supervised by national regulators over the period 2012–2017. The main findings are that bank risk…
Bidirected Information Flow in the High-Level Visual Cortex
2021
Understanding the brain function requires investigating information transfer across brain regions. Shannon began the remarkable new field of information theory in 1948. It basically can be divided into two categories: directed and undirected information-theoretical approaches. As we all know, neural signals are typically nonlinear and directed flow between brain regions. We can use directed information to quantify feed-forward information flow, feedback information, and instantaneous influence in the high-level visual cortex. Moreover, neural signals have bidirectional information flow properties and are not captured by the transfer entropy approach. Therefore, we used directed information …
Synergistic Information Transfer in the Global System of Financial Markets.
2020
Uncovering dynamic information flow between stock market indices has been the topic of several studies which exploited the notion of transfer entropy or Granger causality, its linear version. The output of the transfer entropy approach is a directed weighted graph measuring the information about the future state of each target provided by the knowledge of the state of each driving stock market index. In order to go beyond the pairwise description of the information flow, thus looking at higher order informational circuits, here we apply the partial information decomposition to triplets consisting of a pair of driving markets (belonging to America or Europe) and a target market in Asia. Our …
Patterned Model for Technology Development
1997
This paper develops a perspective to modeling patterned technological information flow processes by drawing on concepts from organizational learning and knowledge creation of high technology enterprises. In such a perspective, humans and their interaction in a development team and in an industry’s ‘invisible college’ are modeled as absorbers and users of technological knowledge. The planning behavior of users is specified in terms of design patterns. A hierarchical multilevel pattern flow and repository model is described. Modes for cooperative technology project work in a case of telecommunication industry domain are examined. Questions regarding the relationship between technological know…
Access Control Model for Cooperative Healthcare Environments: Modeling and Verification
2016
Integrated use of electronic health records (EHRs) seem both promising and necessary in improving the quality and delivery of health services. This allows healthcare providers access to information they require to provide rapid patient care. Of course, when sensitive information is shared among a group of people within or across organizations, enforceable security and privacy control over the information flow is a key aspect. In this study, an access control model for cooperative healthcare environments is presented. A work-based access control (WBAC) model is proposed by introducing the concept of team role and modifying the user-role assignment model from previous work. Verification indic…
A Comparison of the User Experiences of Primary Care Electronic Health Record Systems
2020
Digital health records play an important role for the information flow in primary care organizations that carry out services at patient’s home. Mobile digital solutions have improved the access to up-dated care information at the patient’s home, facilitating new ways for clinical workflow and care delivery. This paper presents a study comparing the user experiences of two electronic health record systems in two primary care organizations in Norway. Qualitative research methods were applied with interviews and observations made between 2017 and 2019 where clinical end-users of primary care electronic health records participated. The study showed that the systems had an important function for…
How to enhance digital support for cross-organisational health care teams? A user-based explorative study
2020
Health care service provision of individualised treatment to an ageing population prone to chronic conditions and multimorbidities is threatened. There is a need for digitally supported care, that is, (1) person-centred, (2) integrated, and (3) proactive. The research project 3P, Patients and Professionals in Productive Teams, aimed to validate and verify the prerequisites for health care systems run with patient-centred service models. This paper presents an explorative study of the digital support of a cross-organisational health care team in Norway, providing services to elderly frail people with multimorbidities in hospital discharge transition. Qualitative research methods were employe…
Distributed correlations and information flows within a hybrid multipartite quantum-classical system
2015
Understanding the non-Markovian mechanisms underlying the revivals of quantum entanglement in the presence of classical environments is central in the theory of quantum information. Tentative interpretations have been given by either the role of the environment as a control device or the concept of hidden entanglement. We address this issue from an information-theoretic point of view. To this aim, we consider a paradigmatic tripartite system, already realized in the laboratory, made of two independent qubits and a random classical field locally interacting with one qubit alone. We study the dynamical relationship between the two-qubit entanglement and the genuine tripartite correlations of …
