Games without repetitions on graphs with vertex disjoint cycles
1997
Games without repetitions on graphs with vertex disjoint cycles are considered. We show that the problem finding of the game partition in this class reduces to this problem for trees. A method of finding of the game partition for trees have been given in [2].
Internacionalización de empresas a través de clústeres: análisis bibliométrico de palabras clave de 152 publicaciones destacadas en el período 2009-2…

[EN] While countless studies on the role of clusters in regional economic developments and business performance have been done, some disadvantages and limitations also have been identified. Limitations such as small local markets, limited resources, isolation, and over-independence which lead companies to a lock-in state regarding knowledge and innovation can be solved by means of internationalization or foreign market expansion. Therefore, the internationalization of clusters still needs more attention. Furthermore, by conducting a bibliometric study based on the keywords from previous research, this investigation intends to identify the principal and most influential items, their relation…
Journalismus aus erzähltheoretischer Perspektive
2018
The essay demonstrates how the narratological theories developed in the field of literary studies can accomplish a better comprehension of journalistic narratives. As they have to accommodate the principles of journalism, these narratives have to be true, topical and impartial. From this point of view storytelling and the inverted-pyramid principle prove themselves as two complementary approaches of journalistic narration, whose stories are all constructed on the basis of real world occurrences and the ideologies of the diverse societies. Storytelling is enabling the communication of individual experience and the inverted-pyramid principle is supporting the narrative construction of future-…
Flernivåstaten og krisehåndtering: En kommentar
2022
Artikkelen diskuterer muligheter og utfordringer knyttet til koordinering på tvers av styringsnivåer. Utfordringen er minst tredelt: Dels knyttet til balansen mellom kontinuitet og endring, nærmere bestemt evnen offentlig forvaltning har til å balansere en stabil kjerne samtidig som den justerer, oppdaterer og reformerer; dels balansen mellom effektivitet og legitimitet, nærmere bestemt evnen til kortsiktig problemløsningen i møtet med kriser og langsiktige utfordringer knyttet til legitime løsninger generelt og parlamentarisk forankring konkret; dels dilemmaet mellom politisk-administrativ orden i turbulente tider, nærmere bestemt hvordan offentlige institusjoner håndterer kriser og vanske…
Sub-nasjonale styringsnivåer i et fler-nivå-administrativt system
2022
Denne artikkelen undersøker hvorvidt respondenter i norske fylkesadministrasjoner oppfatter at sentrale beslutninger influeres av eksterne aktører – gjennom vertikale relasjoner til sentraladministrative instanser og EU/EØS-institusjoner, samt horisontale relasjoner til andre fylkesadministrasjoner – og hvordan variasjonen i slike relasjoner kan forklares. Artikkelen bygger på data fra en ny spørreundersøkelse i norske fylkesadministrasjoner (N = 893), og viser hvordan fylkesadministrasjonene under visse betingelser kan opptre med to eller flere «hatter», det vil si at beslutningene som treffes influeres av flere eksterne aktører samtidig. Hovedtyngden av respondentene oppgir nasjonale sent…
The effect of through-thickness compressive stress on mode II interlaminar fracture toughness
2017
Abstract The effect of through-thickness compressive stress on mode II interlaminar fracture toughness is investigated experimentally and replicated numerically. The modified Transverse Crack Tensile specimen recently proposed by the authors is used, together with an experimental device designed to apply a constant transverse compressive stress on the surface of the specimen. Experiments are conducted using IM7/8552 specimens for different compressive stresses, ranging from 0 to 100 MPa, covering all the practical applications commonly encountered in the aeronautical industry (e.g., tightened filled holes or bolted joints). It is shown that mode II interlaminar fracture toughness increases …
Enhancing Attention’s Explanation Using Interpretable Tsetlin Machine
2022
Explainability is one of the key factors in Natural Language Processing (NLP) specially for legal documents, medical diagnosis, and clinical text. Attention mechanism has been a popular choice for such explainability recently by estimating the relative importance of input units. Recent research has revealed, however, that such processes tend to misidentify irrelevant input units when explaining them. This is due to the fact that language representation layers are initialized by pre-trained word embedding that is not context-dependent. Such a lack of context-dependent knowledge in the initial layer makes it difficult for the model to concentrate on the important aspects of input. Usually, th…
A multi-step finite-state automaton for arbitrarily deterministic Tsetlin Machine learning

What is it about humanity that we can't give away to intelligent machines? A European perspective
2021
Abstract One of the most significant recent technological developments concerns the development and implementation of ‘intelligent machines’ that draw on recent advances in artificial intelligence (AI) and robotics. However, there are growing tensions between human freedoms and machine controls. This article reports the findings of a workshop that investigated the application of the principles of human freedom throughout intelligent machine development and use. Forty IS researchers from ten different countries discussed four contemporary AI and humanity issues and the most relevant IS domain challenges. This article summarizes their experiences and opinions regarding four AI and humanity th…
Learning Automata-based Misinformation Mitigation via Hawkes Processes
2021
AbstractMitigating misinformation on social media is an unresolved challenge, particularly because of the complexity of information dissemination. To this end, Multivariate Hawkes Processes (MHP) have become a fundamental tool because they model social network dynamics, which facilitates execution and evaluation of mitigation policies. In this paper, we propose a novel light-weight intervention-based misinformation mitigation framework using decentralized Learning Automata (LA) to control the MHP. Each automaton is associated with a single user and learns to what degree that user should be involved in the mitigation strategy by interacting with a corresponding MHP, and performing a joint ra…
