Energy efficiency and CO₂ emission reduction are key objectives related to climate change mitigation, sustainable development, and energy resource management. In the Nordic context, energy consumption trends in both the residential and industrial sectors are closely linked to European Union policies, technological innovation, and real estate investments. In recent decades, the development and renovation of the real estate sector has become one of the most important factors determining changes in energy consumption, especially in residential buildings, which remain among the largest energy consumers and polluters. In this context, countries’ efforts to reduce CO₂ emissions and increase energy efficiency are inseparable from the real estate sector’s contribution to these processes, by promoting investments in building modernization and energy-saving technologies. However, the real estate sector remains a complex area where economic interests need to be reconciled with environmental objectives, especially in the context of EU strategies such as the Renovation Wave and the Energy Efficiency Directive. This article examines the links between real estate investment, energy efficiency, and CO₂ emission reduction, based on quantitative analysis, to assess how the development of the real estate sector and EU policy measures affect sustainable development in Northern Europe. This study uses advanced quantitative methods, including a panel regression model, which helps better reveal the long-term dependencies between investment, energy consumption, and emissions dynamics. This article highlights the importance of the real estate sector in implementing sustainability policies and suggests strategic solutions that can help reconcile economic and environmental priorities.

This article investigates the concept of hospitality (xenia) in the ancient Mediterranean world and its relevance to contemporary migrant communities. To bridge the gap between ancient texts and modern experiences, we utilize a combined lens of contextual biblical hermeneutics and migration theory to analyze the Parable of the Returning Son (Luke 15:11–32), highlighting the inherent tensions and complexities of welcoming the stranger. Ethnographic research among Latin Pentecostal migrant congregations in the Nordic countries reveals how these communities embody xenia through tangible acts of welcome, risk-taking, and prodigal hospitality. This analysis demonstrates the vital role of hospitality in fostering community building within contexts of mobility. Furthermore, the concept of xenia helps address the limitations of applying modern migration theories directly to ancient contexts by providing a framework for understanding the continuity and evolution of hospitality practices across time and cultures.

In today’s globalized world, more children are born to parents who speak two or more languages between them. These families manage complex language dynamics, with diverse language practices influencing communication among family members. The complexity intensifies when multilingual and multicultural parents move with their children to a country with a new majority language, while keeping connections to their original society. In such cases, balancing heritage and host country languages affects both cultural preservation and integration into a new society. Based on semi-structured interviews with seven Generation 1.5 Russian–Hebrew bilingual parents living in Finland, this paper explores their strategies for managing their children’s multilingual development. The study poses two key questions: What are the language management strategies reported by the parents? What are the major challenges these parents face in maintaining heritage Russian and Hebrew languages in Finland? Thematic data analysis using ATLAS.ti software highlights the parents’ persistent commitment to maintaining multilingualism within their families, focusing on preserving existing social connections and fostering new ones for the entire family. The findings reveal key aspects of parental language management, parental involvement and home environments, along with reported challenges, both personal and institutional, in maintaining Hebrew and Russian as heritage languages in Finland. This study offers a new perspective on language management strategies in multilingual families, handling a less-explored language combination. By analyzing individual language management approaches, this study reveals common strategies used to support multilingualism and balance heritage languages with those of a new environment, thereby contributing to discussions on linguistic diversity and multicultural integration in transnational settings.

Residential wood combustion (RWC) is a significant source of gaseous and particulate emissions causing adverse health and environmental effects. Several factors affect emissions, but the effects of the fuel wood species on emissions are currently not well understood. In this study, the Nordic wood species (named BirchA, BirchB, Spruce, SpruceDry, Pine and Alder) were combusted in a modern stove, and the emissions were studied. The lowest emissions were obtained from the combustion of BirchA and the highest from Spruce and Alder. The fine particle mass (PM_2.5) was mainly composed of elemental carbon (50–70% of PM_2.5), which is typical in modern appliances. The lowest PAH concentrations were measured from BirchA (total PAH 107 µg/m³) and Pine (250 µg/m³). In the ignition batch, the PAH concentration was about 4-fold (416 µg/m³). The PAHs did not correlate with other organic compounds, and thus, volatile organic compounds (VOCs) or organic carbon (OC) concentrations cannot be used as an indicator of PAH emissions. Two birch species from different origins with a similar chemical composition but different density produced partially different emission profiles. This study indicates that emission differences may be due more to the physical properties of the wood and the combustion conditions than to the wood species themselves. Full article

Arranging products in stores according to planograms, optimized product arrangement maps, is an important sales enabler and necessary for keeping up with the highly competitive modern retail market. Key benefits of planograms include increased efficiency, maximized retail store space, increased customer satisfaction, visual appeal, and increased revenue. The planograms are realized into product arrangements by humans, a process that is prone to mistakes. Therefore, for optimal merchandising performance, the planogram compliance of the arrangements needs to be evaluated from time to time. We investigate utilizing a computer vision problem setting—retail product detection—to automate planogram compliance evaluation. Retail product detection comprises product detection and classification. The detected and classified products can be compared to the planogram in order to evaluate compliance. In this paper, we propose a novel retail product detection pipeline combining a Gaussian layer network product proposal generator and domain invariant hierarchical embedding (DIHE) classifier. We utilize the detection pipeline with RANSAC pose estimation for planogram compliance evaluation. As the existing metrics for evaluating the planogram compliance evaluation performance assume unrealistically that the test image matches the planogram, we propose a novel metric, called normalized planogram compliance error $\left(E_{PC}\right)$, for benchmarking real-world setups. We evaluate the performance of our method with two datasets: the only open-source dataset with planogram evaluation data, GP-180, and our own dataset collected from a large Nordic retailer. Based on the evaluation, our method provides an improved planogram compliance evaluation pipeline, with accurate product location estimation when using real-life images that include entire shelves, unlike previous research that has only used images with few products. Our analysis also demonstrates that our method requires less processing time than the state-of-the-art compliance evaluation methods. Full article

The monastic archives of Iceland have rarely been made the subject of specific studies. This article is intended to survey the history of one such archive, belonging to the Benedictine Abbey of Þingeyrar in Northern Iceland, which was founded 1133 and dissolved 1551. Through its extraordinarily rich literary production this monastery left an indelible mark on the Northern-European cultural heritage. After the Reformation Þingeyrar Cloister remained a state-owned and ecclesiastical institution until modern times. Its archive, which is partly preserved to this day, is both the most extensive of its kind to survive in Iceland and uniquely remained in place for almost eight centuries, making it possibly the longest operated archive in the Nordic countries. The Icelanders may be better known for their sagas and mythological poetry, but their industrious literacy certainly extended to creating bureaucratic documents in accordance with the Roman tradition. French Benedictines were among the first in the world to turn the art of archival management into an academic discipline, and the Icelandic Professor Árni Magnússon (d. 1730), who is best known for his great collection of Old Icelandic manuscripts, was the first Nordic scholar to employ their methods effectively, which he used to investigate the Archive of Þingeyrar. Surveying the history of this Icelandic archive gives us insight into a constitutive science fundamental for our access to the past. Full article

In the course of the twentieth century, the glorified image of Viking Age Scandinavia exerted an increasing attraction on intellectuals and nation builders in remote parts of Europe, especially those which self-identified as peripheral, marginalized, and ‘northern’. In the Dutch province of Friesland, the cultivation of a Frisian national identity went hand in hand with an antagonizing process of self-contrastation vis-à-vis the urbanized heartland in the west of the country. Fueled by these anti-Holland sentiments, the adoption of Nordic identity models could serve to create alternative narrative molds in which to cast the Frisian past. In this article, I will chart this process of cultural “nordification” from its initial phase in the writings of Frisian Scandinavophiles to contemporary remediations of Frisian history in popular culture and public discourses. In this context, special attention will be paid to the reception history of the pagan King Redbad (d. 719) and his modern transformation from ‘God’s enemy’ to beloved national icon. Full article

Information on dietary adequacy is needed to assess food and nutrition security in a modern society, especially in the transition towards climate-friendly food systems. In this study, differences in the nutritional adequacy of diets among Finnish adults were evaluated in population groups of different education, income and urbanisation levels. The study used data from the FinDiet 2017 Survey (n = 1655, 18–74 years). Modelled usual intakes of foods and nutrients were evaluated relative to food-based dietary guidelines issued by the National Nutrition Council of Finland (FNNC) and with respect to nutrient adequacy following the Nordic Nutrition Recommendations and FNNC. For about half of the nutrients studied, intakes were found to be adequate. Intakes of protein, fat, saturated fatty acids and salt were estimated to be high. By contrast, inadequate intakes were seen in folate and vitamins A, D, B1, B2 and C in almost all groups studied. Groups with a higher education and income, groups that lived in urban areas and, in particular, women adhered more closely to recommended food consumption and nutrient intakes than others. However, major challenges posed by the Finnish diet are common to all groups studied, and only certain dietary features evaluated in view of nutritional adequacy are associated with socioeconomic differences.

The paper analyses the performance of a five-storey apartment building equipped with modern passive stack ventilation in Nordic conditions. The passive stack ventilation system was retrofitted in 2019, and novel self-regulating air inlet devices with filters were equipped. The building was simulated with IDA ICE software, where the model of the self-regulating terminal units was developed using manufacturer product data. Several case scenarios were created to analyze the effects of poor maintenance, improved airtightness, and window opening on the system performance. For the analysis, one-room and three-room apartments on the second and fifth floors have been chosen. The CO₂ concentration and indoor air temperature were analyzed and compared with EN 16798-1 standard guidelines. The results show a significant effect of poor maintenance and possibility to open windows on the CO₂ concentration. The results also show a trend for the one-room apartments to overheat despite having a higher air change rate than the three-room apartments. The three-room apartments tolerate over-heating, although they are much more sensitive to poor maintenance. Furthermore, the apartments on the fifth floor are even more sensitive to poor maintenance, and three-room apartments there showed warning levels of CO₂. Improving the envelope airtightness does not benefit the IAQ of the apartments. Full article

In Lithuania, there are two recognised native sheep breeds: old native Lithuanian Coarsewooled and Lithuanian Blackface. In addition, in 2005, primitive Heidschnucke-type Skudde sheep were imported to Lithuania and were argued to possibly represent a lost Lithuanian sheep type. The aim of the study was to investigate the genetic variation in the two Lithuanian native sheep breeds, compare them with the imported Skudde sheep and establish the historical patterns of admixture and the genetic relatedness of Lithuanian sheep to British, Central European and Nordic sheep breeds included in the SheepHapMap study. In total, 72 individuals, representing two Lithuanian native and imported Skudde sheep breeds, were genotyped using a Neogen 12K Illumina Infinium chip. The population analysis was carried out by model-based clustering, principal component analysis and neighbour net analysis, and showed similar patterns for the Lithuanian sheep populations. Lithuanian Coarsewooled and Skudde in Lithuania have unique divergence and possibly some shared ancestry, while the Lithuanian Blackface conforms to a modern synthetic breed. The study clearly showed that the Coarsewooled and the Skudde breeds are distinct from each other. Historical data strongly suggest that the Coarsewooled breed represents a local breed, while the Skudde origin is less directly linked to the geographical area of modern-day Lithuania. Within the modern-day Lithuanian context, the Lithuanian Coarsewooled sheep is very important historical sheep type for conservation. Full article

Withthe massive penetration of electronic power converter (EPC)-based technologies, numerous issues are being noticed in the modern power system that may directly affect system dynamics and operational security. The estimation of system performance parameters is especially important for transmission system operators (TSOs) in order to operate a power system securely. This paper presents a Bayesian model to forecast short-term kinetic energy time series data for a power system, which can thus help TSOs to operate a respective power system securely. A Markov chain Monte Carlo (MCMC) method used as a No-U-Turn sampler and Stan’s limited-memory Broyden–Fletcher–Goldfarb–Shanno (LM-BFGS) algorithm is used as the optimization method here. The concept of decomposable time series modeling is adopted to analyze the seasonal characteristics of datasets, and numerous performance measurement matrices are used for model validation. Besides, an autoregressive integrated moving average (ARIMA) model is used to compare the results of the presented model. At last, the optimal size of the training dataset is identified, which is required to forecast the 30-min values of the kinetic energy with a low error. In this study, one-year univariate data (1-min resolution) for the integrated Nordic power system (INPS) are used to forecast the kinetic energy for sequences of 30 min (i.e., short-term sequences). Performance evaluation metrics such as the root-mean-square error (RMSE), mean absolute error (MAE), mean absolute percentage error (MAPE), and mean absolute scaled error (MASE) of the proposed model are calculated here to be 4.67, 3.865, 0.048, and 8.15, respectively. In addition, the performance matrices can be improved by up to 3.28, 2.67, 0.034, and 5.62, respectively, by increasing MCMC sampling. Similarly, 180.5 h of historic data is sufficient to forecast short-term results for the case study here with an accuracy of 1.54504 for the RMSE. Full article

This article discusses the concept of modernism, as reflected for instance in attempts to find a manageable narrative frame for the history of literary modernism. The article argues that this attempt is complicated by modernism as an unruly and complex trend that manifests itself in different ways, and at different moments, as it enters into a complex dialogue with other trends within various linguistic communities. These different times and places of modernism also turn out to interact with one another through translations and other forms of reception that sometimes entail renewed modernist creativity. Discussing these significant aspects of modernism, the article also considers the problems critics of modernism face as they attempt to come up with a narrative framework for the history of modernism and its ongoing relationship with realism. A key point argued in the article is that to come to terms with both these trends we need to appreciate the ways in which modernism is linked to historical crises and traumas of our time, including the first and the second world wars. Paying particular attention to the interplay of Nordic and European modernisms, the article discusses how aspects of modernism have manifested themselves in Iceland, a Nordic island which may seem doubly removed from the European centres of modernism in cities such as London and Paris.

Sustainability and energy efficiency have become important factors for many industrial processes, including chemical pulping. Recently complex back-end heat recovery solutions have been applied to biomass-fired boilers, lowering stack temperatures and recovering some of the latent heat of the moisture by condensation. Modern kraft recovery boiler flue gas offers still unutilized heat recovery possibilities. Scrubbers have been used, but the focus has been on gas cleaning; heat recovery implementations remain simple. The goal of this study is to evaluate the potential to increase the power generation and efficiency of chemical pulping by improved back-end heat recovery from the recovery boiler. Different configurations of heat recovery schemes and different heat sink options are considered, including heat pumps. IPSEpro simulation software is used to model the boiler and steam cycle of a modern Nordic pulp mill. When heat pumps are used to upgrade some of the recovered low-grade heat, up to +23 MW gross and +16.7 MW net power generation increase was observed when the whole pulp mill in addition to the boiler and steam cycle is considered as heat consumer. Combustion air humidification proved to yield a benefit only when assuming the largest heat sink scenario for the pulp mill. Full article

A socially-engaged literary Modernist, whose writings possess an incisive skepticism toward political power, Eyvind Johnson (1900–1976) was a working-class autodidact who became a prominent voice in Swedish letters during the twentieth century. His historical novels have attracted the most critical attention to date, but his short fiction from the 1920s reveals a young author increasingly suspicious of what postmodern theorist Jean-Francois Lyotard would later call master narratives—totalizing views of historical events that serve a political or universalized function. In “Kort Besök” (A Short Visit), “Det Förlorade Europa,” (The Lost Europe) and “En Man i Etolien” (A Man in Aetolia), from his 1932 short story collection Natten är här (The Night Has Come), Johnson’s characters resist and subvert various master narratives, maintaining their dignity and individuality in the face of destructive political, military or nationalistic agendas. Although his formal experimentation, introspective storytelling and narrative irresolution firmly situate him in the Modernist literary tradition, Johnson’s disruption of grand narratives about historical events in these stories previews postmodernity, with its radical interrogation of language’s subjugating power, suggesting a new avenue for evaluating and apprehending his literary innovations. Short fiction, thus, offers an accessible entryway into the complex art of Eyvind Johnson, whose intricate novels about centuries past have long resisted casual readership. Full article
