Digital Twins (DTs) are increasingly recognized as a strategic technology for enhancing cybersecurity in industrial environments, particularly in the face of rising threats targeting Operational Technology (OT). After comparatively examining closely related DT–cybersecurity frameworks to position the contribution within the existing research landscape, this paper presents a systematic literature review and comparative analysis of 19 recent DT-based cybersecurity studies, focusing on their relevance to incident detection and response in sectors such as Industrial Internet of Things (IIoT), manufacturing, and energy. The analysis evaluates each study across multiple dimensions, including attack types, detection and response mechanisms, DT integration, and technology stacks. From this review, we derive a consolidated set of requirements, categorized as functional, non-functional, security-specific, and domain-specific. These requirements serve as the foundation for a novel, cybersecurity-focused, ISO 23247-based framework. The proposed architecture formalizes a DT-enabled incident detection and response lifecycle aligned with ISO 23247. It is explicitly mapped to the derived requirements and detailed with practical implementation considerations. This work contributes a structured, evidence-based approach to DT-based security engineering and offers a reference design for researchers and practitioners aiming to build resilient, adaptive cybersecurity solutions in industrial settings.

Finfish aquaculture is one of the fastest-growing food production sectors in the world, and numerous infectious diseases are a constant challenge to the fish farming industry, causing decreased fish health and, consequently, economic losses. Specific and sensitive tools for pathogen detection are crucial for the surveillance of environmental samples to prevent the spread of fish pathogens in farms. Monitoring of waterborne pathogens through filtration of water and subsequent molecular detection of target-specific DNA or RNA sequence motifs is an animal-friendly method. This approach could reduce or even replace the sacrifice of fish for monitoring purposes in aquaculture and allow earlier implementation of disease control measures. Sampling methods might be a bottleneck, and there is a need for simple sampling methods that still ensure the best detection probability. In this study, we tested different filtration methods with spiked freshwater and seawater for a panel of fish pathogens to discern a suitable procedure that can be easily applied on-site by farm personnel without compromising detection probability. Specifically, we tested combinations of different filtration flow rates, lysis buffers, and filters for the detection of some of the pathogens relevant to the aquaculture industry. The results showed that a “sandwich” filtration method using two different filters and a flow rate of up to 4.0 L/min ensured good pathogen detection. The filters, consisting of a hydrophilic glass fibre filter with binder resin on the top and a hydrophilic mixed cellulose esters membrane at the bottom, achieved the best concentration and qPCR detection of both viral and bacterial fish pathogens. This up-and-coming tool allows the detection of very different fish pathogens during a single filtration step, and it can be combined with one single automated total nucleic acid extraction step for all the investigated pathogens, reducing both analysis costs and time.

Rising organic charge in northern freshwaters is attributed to increasing levels of dissolved natural organic matter (DNOM) and changes in water chemistry. Organic charge concentration may be determined through charge balance calculations (Org.−) or modelled (OAN−) using the Oliver and Hruška conceptual models, which are based on the density of weak acid functional sites (SD) present in DNOM. The charge density (CD) is governed by SD as well as protonation and complexation reactions on the functional groups. These models use SD as a key parameter to empirically fit the model to Org.−. Utilizing extensive water chemistry datasets, this study shows that spatial and temporal differences in SD and CD are influenced by variations in the humic-to-fulvic ratio of DNOM, organic aluminum (Al) complexation, and the mole fraction of CD to SD, which is governed by acidity. The median SD values obtained for 44 long-term monitored acid-sensitive lakes were 11.1 and 13.9 µEq/mg C for the Oliver and Hruška models, respectively. Over 34 years of monitoring, the CD increased by 70%, likely due to rising pH and declining Al complexation with DNOM. Present-day median SD values for the Oliver and Hruška models in 16 low-order streams are 13.8 and 15.8 µEq/mg C, respectively, and 10.8 and 12.5 µEq/mg C, respectively, in 10 high-order rivers.
Based on available information on nudibranchs from all published literature, sampling concentrated around the area of Central Norway, and the nudibranch collections at the Museum of Natural History and Archaeology in Trondheim, this study presents the distribution of nudibranch species along the Norwegian coast. All species reported in the literature from Norwegian waters are listed and discussed. A total of 81 species are confirmed being a part of the Norwegian fauna, of which four species (Cuthona rubescens, Polycera faeroensis, Eubranchus vittatus and Onchidoris depressa) are new to Norwegian waters, and two that have previously been mentioned but not documented, Cuthona caerulea and Geitodoris planata, are confirmed found for the first time. Six species, Triopella incisa, Cadlina glabra, Rostanga setidens, Cuthona distans, Cuthona norvegica, Berghia norvegia are considered endemic to Norway, and four species, Doridunculus echinulatus, Doris nobilis, Doto crassicornis, Goniaeolis typica are considered endemic to Scandinavian waters. After the review six species previously reported from Norwegian waters, are considered insufficiently supported, or due to misidentifications (Onchidoris aspersa, Onchidoris oblonga, Onchidoris sparsa, Thecacera virescens, Doto tuberculata and Flabellina browni) and are not longer considered a part of the Norwegian fauna. Sampling has in large been based on SCUBA diving, and proved to be very efficient when sampling in the upper sublittoral in kelp forest habitat.
The aged photo of a ship would normally not determine you to return to the first pages of a text and read it again and again. But if you are the reader of Lars Saabye Christensen’s new book, Min kinesiske farmor [My Chinese grandmother], it does. Because Lars Saabye Christensen’s text is not only a book about the journey to China that the narrator’s grandmother took in 1906, but it is in fact a journey in itself. It takes the reader from the present to the near and far past, from Norway to Denmark and China, as it renders the power of memory and love and the changes that come along with the passing of time. Bunica mea chinezoaică [My Chinese Grandmother] is admirably translated from Norwegian and Danish by Professor Sanda Tomescu Baciu, with the financial support of NORLA (Norwegian Literature Abroad) and appeared in 2022 at Casa Cărții de Știință publishing house. It brings a flood of memories revolving around S/S Protector, whose picture we can see on the cover of the Romanian translation of the novel, thanks to Professor Sanda Tomescu Baciu and M/S Maritime Museum of Denmark.
Heritage Norwegian in the American Midwest is documented through a corpus of recordings collected and compiled over a time span of 80 years, from Einar Haugen’s recordings in the 1940s via the CANS corpus up to the present-day in the authors’ own recordings. This gives an unprecedented opportunity to study how a minority language changes in a language contact situation, over several generations and under gradually changing circumstances. Since we also have thorough historical knowledge of the institutions and societal texture of these communities, this privileged situation allows us to trace the various sources of input available to the heritage speakers in these communities in different relevant time slots. We investigate how the quality and quantity of input at different times are reflected in the syntactic production of heritage speakers of the corresponding generational cohorts, focusing on relative ratios of specific word orders (topicalization and verb second, prenominal and postnominal possessive noun phrases) and productive morphosyntactic paradigms (tense suffixes of loan verbs). Utilizing a model of relations between input and output, receptive and productive competence, to show how input–output effects will accumulate throughout the cohorts, we explain the observed linguistic change in individuals and society.

Abstract Background There are a substantial number of children who are the next of kin of parents suffering from illness or substance abuse. These children can experience emotional and behavioral problems and may need support from professionals. In Norway, the specialist health service in hospitals is required to have a designated practitioner in each department to ensure support for and follow up of children who are next of kin; however, this is not regulated by law in the health care in the municipalities. The aim of this study was to explore public health nurse’s experiences working with children who are next of kin. Methods Qualitative interviews were conducted with 10 public health nurses working in the child health clinic and the school health service in four municipalities. Data were analysed using content analysis. Reporting of this study is conducted in accordance to COREQ’s checklist. Results The analysis resulted in one main theme: ‘Lack of guidelines and routines among public health nurses working with children who are next of kin’. The main theme consisted of four categories: (1) identifying children who are next of kin are incidental; (2) public health nurses must be observant and willing to act; (3) communication is an important tool; and (4) follow up over time is not always provided. Conclusion The public health nurses experienced uncertainty concerning how to identify and follow up children who are next of kin but were vigilant and willing to act in the children’s best interest. Doing so necessitated collaboration with other professionals. The need for guidelines around the role and responsibilities for the public health nurse were emphasized. The knowledge provided by the current study offers valuable insight into strengths and limitations in the support of children who are next of kin and can inform stakeholders in organizing sustainable support for this group.
Abstract Human life expectancy increases, but the disease-free part of lifespan (healthspan) and the quality of life in old people may not show the same development. The situation poses considerable challenges to healthcare systems and economies, and calls for new strategies to increase healthspan and for sustainable future approaches to elder care. This call has motivated innovative research on the role of social relationships during ageing. Correlative data from clinical surveys indicate that social contact promotes healthy ageing, and it is time to reveal the causal mechanisms through experimental research. The fruit fly Drosophila melanogaster is a prolific model animal, but insects with more developed social behaviour can be equally instrumental for this research. Here, we discuss the role of social contact in ageing, and identify lines of study where diverse insect models can help uncover the mechanisms that are involved. This article is part of the theme issue ‘Ageing and sociality: why, when and how does sociality change ageing patterns?’
The present article critiques the so-called postcritical position for refusing to acknowledge the literariness of literature. As a case in point, it considers Toril Moi’s Revolution of the ordinary: literary studies after Wittgenstein, Austin, and Cavell, which has been greeted as a pivotal specimen of postcritique. Like other practitioners of postcritique, Moi would replace literary theory with an art of judgment, based upon good faith in, rather than suspicion of, the literary text. In theory, all that is needed to practice this art of judgment is a willingness to pay close attention to the specifics of the particular case. In practice, however, the postcritical claim to go beyond ‘the hermeneutics of suspicion’ is compromised by its refusal to confront the literariness of literary text, as the present essay demonstrates by subjecting Moi’s own reading of the particular cases of Paul de Man and Norwegian terrorist Anders Behring Breivik to rhetorical analysis.
The North Atlantic is one of the major sinks for anthropogenic carbon in the global ocean. Improved understanding of the underlying mechanisms is vital for constraining future projections, which presently have high uncertainties. To identify some of the causes behind this uncertainty, this study investigates the North Atlantic’s anthropogenically altered carbon uptake and inventory, that is, changes in carbon uptake and inventory due to rising atmospheric CO2and climate change (abbreviated as [Formula: see text]-uptake and [Formula: see text]-inventory). Focus is set on an ensemble of 11 Earth system models and their simulations of a future with high atmospheric CO2. Results show that the model spread in the [Formula: see text]-uptake originates in middle and high latitudes. Here, the annual cycle of oceanic pCO2reveals inherent model mechanisms that are responsible for different model behavior: while it is SST-dominated for models with a low future [Formula: see text]-uptake, it is dominated by deep winter mixing and biological production for models with a high future [Formula: see text]-uptake. Models with a high future [Formula: see text]-uptake show an efficient carbon sequestration and hence store a large fraction of their contemporary North Atlantic [Formula: see text]-inventory below 1000-m depth, while the opposite is true for models with a low future [Formula: see text]-uptake. Constraining the model ensemble with observation-based estimates of carbon sequestration and summer oceanic pCO2anomalies yields later flattening of the [Formula: see text]-uptake than previously estimated. This result highlights the need to depart from the concept of unconstrained model ensembles in order to reduce uncertainties associated with future projections.
This article discusses the impact of convergence and digital intermediaries for television as a medium, industry and political and cultural institution. There is currently widespread debate about the future of television and the impact of technological and market changes. Our argument is that the answer to what is happening to television cannot be adequately addressed on a general level; local and contextual factors are still important, and so is the position and strategic response of existing television institutions in each national context. Based on analyses of political documents, statistics, audience research and media coverage, as well as secondary literature, the article explores the current situation for Norwegian television and point to four contexts that each plays a part in constraining and enabling existing television operators: the European context, the public service context, the welfare state context and the media ecosystem context.

Quantum physics and relativity are demanding for teachers and students, but have the potential for students to experience physics as fascinating and meaningful. Project ReleQuant engaged in educational design research to improve teaching and learning in these topics in Norwegian upper secondary schools. The paper focuses on the first cycle of development of a teaching module on quantum physics and how design principles were developed. We construct the design principles by reviewing relevant research literature and conducting three pilot studies. The process resulted in the following principles for designing the quantum physics teaching module: 1) clarify how quantum physics breaks with classical physics; 2) use simulations of phenomena that cannot be experienced directly; 3) provide students to use written and oral language; 4) address and discuss wave-particle duality and the uncertainty
Teesid: Oktoobrirevolutsiooni järgne vene emigratsioon, mida teaduskirjanduses traditsiooniliselt nimeta takse esimeseks laineks, valgus mööda ilma laiali ning oli seninägematult arvukas, haarates kaasa miljoneid endise Tsaari-Venemaa elanikke. Sellele nähtusele on pühendatud tuhandeid humanitaartea duslikke, sotsioloogilisi, politoloogilisi jm uurimusi, mis kajastavad vene eksiilkultuuri eri tahke. Vene emigratsioon puudutas ka Eestit ning enamik käsitletud ilmingutest olid otseselt seotud siinse vene kogukonnaga, ent kohati väga erineva tähendusega. Käesoleva artikli eesmärk on lühidalt kirjeldada vene emigratsiooni sotsiaalset ja demograafilist struktuuri, selle keskusi, emigrantide rolli oma ja võõra kultuuri säilitamisel, põlvkondadevahelist aspekti, eelkõige kirjanduselus, ning haridusküsimusi. Lähemalt on käsitletud vene emigrantide rolli Eesti kultuuris muu maailma taustal.

After the October Revolution a mass of emigrants, all citizens of the former Tsarist Russia dispersed in the world. In the scholarly literature this dispersal of upwards of a million people has come to be referred to as the first wave of Russian emigration. Thousands of scholarly articles from the humanities, sociology, political science and other disciplines have been devoted to various aspects of Russian exile culture: descriptions of exile cultural centres (including Paris, Berlin, Constantinople, Brazil, and the USA); various cultural phenomena (literature, film, theatre, fashion, journalism, art, etc.). As was true of the large part of Europe, the Russian emigration impacted Estonia, as it did across the rest of Europe; however, the fate of the Russian community in Estonia had strikingly original features. Some of these derived principally from Estonia’s position as a border state, as well as from the fact that even in the days of the Russian Empire, over 40000 Russians resided in Estonia. Theoretically, this should have made it easier for Russian emigrants to assimilate to Estonian conditions (for example, Russian schools existed from an earlier period, along with the requisite complement of teachers; Russian-language journalism existed, etc.). However, in reality, most of the promoters of local Russian culture emerged from among the emigrants, new settlers in Estonia.
The purpose of this article is briefly to describe the social and demographic structure of the Russian emigration (military personnel will be treated separately) and the question of their legalization, which was solved in 1921 by the renowned Norwegian explorer Fridtjof Nansen. At his initiative, the Intergovernmental Conference of the representatives of 34 nations that met in Geneva adopted the designation refugee, which for the time being only referred to stateless people of Russian origin. The legitimation of these people as refugees was contingent on the acceptance of a statute confirming the use of a heretofore nonexistent International identity document, the so-called Nansen Certificate. This certificate enabled Russian emigrants to claim refugee status in several nations, which included the attribution of rights and freedoms equal to those of citizens of these nations. Approximately 450 000 Nansen Certificates were issued over a period of several years.
The article contains brief descriptions of centres of exile, the circumstances and chronology of their foundation, the perceived role of emigrants in the preservation of their own culture and a culture foreign to them. The intergenerational conflict that occurred in cultural, in particular literary life is discussed. Among other topics considered are issues concerning publication, journalistic activity, and educational activities; a brief consideration is given to the positions of different nations on the support and preservation of Russian-language education. A very important influence on Russian emigration was Vladimir Lenin’s so-called „gift“— the expulsion of over 200 scholars from Soviet Russia in the year 1921.
A special place is accorded in this article to the role of Russian emigrants in Estonian culture, including the role played by Russian cultural figures (scholars, military personnel, artists, etc.) in building up the young Estonian Republic. The most active participation of Russians was occasioned by the creation of Estonia’s own legal system. In addition, Russians participated in organizing the Estonian postal system and local transportation. The role of Russian emigrants in the development of the educational system of the Estonian Republic is also significant. The article describes the leadership provided by the local Russian community, particularly in the establishment in 1924 of the tradition of Russian cultural festivals, which was then disseminated globally in Russian exile culture.
Brief consideration is given to local Russian culture and its importance in the development of Estonian culture. The most important facet of this was the Estonian ballet, born of Russian traditions and experience. Reportedly the first professional ballet troupe was assembled in Tallinn in 1918 by Sessy Smironina-Sevun, but the first actual ballet was performed in 1922, premiering with Coppelia, choreographed by the Moscow Bolshoi Ballet prima ballerina Viktorina Krieger, who played the lead role, and was later to be the artistic director of the Estonia ballet. In 1919, Jevgenia Litvinova, a former ballerina from the Maria Theatre, founded the first ballet studio in Tallinn.
Another topic addressed in the article is local publishing and literary activity in the Russian language. Besides Russian publishing houses (Bibliofiil, Koltso, Alfa, Russkaja Kniga), Estonian-language publishing houses printed Russian-language books, textbooks, magazines and newspapers. Up to the year 1940, 91 publishing houses in Estonia printed Russian-language material, many of them only a few Russian books. In addition to publication activities, literary circles were active at different times. Among them was the Revel Literary Circle, founded in 1898, the oldest and most unusual gathering place for educated people. Poets’ workshops in Tallinn and Tartu were among the more interesting societies in Estonia, aimed more specifically at poets of the younger generation. Members of the Tallinn workshop created their own almanac, „Nov“, and published a magazine, Polevõje Tsvetõ.
All of these phenomena and problems must be situated in the context of the larger world. The Russian emigration is far from being merely a unique phenomenon of life and work outside of the homeland; indeed, it exerted a strong influence on the culture, scholarship, and literature of the countries of settlement. Among the greatest achievements of 20th century humanity are the works of Nobel laureate and writer Ivan Bunin, prose writer Vladimir Nabokov, artists Marc Chagall, Konstantin Korovin, Aleksander Benois, and Vassily Kandinsky; the theories of Noble laureate, physicist and chemist Ilya Prigogine; the works of composers Sergei Rachmaninoff, and Igor Stravinsky; actor and theatre director Mikhail Chekhov; constructor Igor Sikorsky; chemist Vladimir Ipatjev. No less important in Estonian culture were poet Igor Severjanin, architect Aleksander Vladovski, representatives of Russian classical ballet (Tamara Beck, Jevgenia Litvinova); artists Anatoli Kaigorodov, Nikolai Kalmakov, and Andrei Jegorov.
In his book from 1865 Johan Kulstad tells the story of a hunting expedition to Spitzbergen in 1853. The mother ship disappears, and in desperation Kulstad and his six men starts rowing their small hunting boat back to Norway. After six days of incredible suffering, they are rescued by a Danish ship a few miles off the coast of Finnmark. After outlining the main sides of this story, the article comments briefly on the way Kulstad tells his story: There is a mixture of pre-realistic and naturalistic narrative, there is a mixture of genres, and the text is without the heroism which is so prevalent in later Arctic narrative. Interesting detail: The way a Sami member of the expedition is portrayed
A year after the French success scandal that Rachilde had with her decadent novel Monsieur Vénus, a novel by the Swedish writer Victoria Benedictsson, Money [Pengar], is published in Sweden in 1885. The two novels focus on young women having to find their identities within society's new possibilities, as well as the new gender roles; developed by the new society. In their relations with both conventional and non-conventional male characters, the two female characters transgress society's former established and given norms. In this article, the aim is to present how two female protagonists, the French Raoule and the Swedish Selma, are given different background conditions and qualities that finally can contribute to picture and explain their outstanding independence. Moreover, the new gender roles and their impact on the two female characters are discussed within themes and terms such as the "new woman", androgynity, sexuality and other explicite ingredients and symbols often discussed in a decadent context. Through the comparisons, this article shows how the two female portraits express the decadent transgressivity, in several aspects similarly, with individual voices, despite their two separate literary milieux.
Culture has always been one of the most neglected aspects of the critical analysis of cross-border cooperation. It is the least studied and least understood aspect of international cooperation. That's why it is clear that the study of culture and cross-border cooperation is needed now. The
subject of this article is cultural cooperation between the Murmansk region, the Scandinavian countries and Finland. This article will examine cooperation in the field of libraries and literature studies, and cooperation in the exhibition and management of the museums within this Region.
Around 1967 and onwards, Per Højholt (1923-2004) performs a series of punctures in the periphery of a small and self-conscious avant-garde in Denmark - experiments that combine most of the known art forms and genres in a still more active dialogue with new media and technology.
One of the first things Højholt engaged himself in at the time was Show-Bix, which is best described as an artist group consisting of the photographer and visual artist Poul Ib Henriksen, composer Gunner Møller Pedersen, and Per Højholt (at the time described largely as a poet). The group was operative from 1968 and until 1971, a period during which it conducted a series of complex experiments involving an audience as well as a media consciousness which is quite unique in Denmark - perhaps even more so today. In fact, I claim that Show-Bix is the visible proof of a paradigmatic change in Per Højholt's artistic practice, as well as in the overall definition of the contemporary art scene.
