e-Learning is a sought-after option for learners during pandemic situations. In e-Learning platforms, there are many courses available, and the user needs to select the best option for them. Thus, recommender systems play an important role to provide better automation services to users in making course choices. It makes recommendations for users in selecting the desired option based on their preferences. This system can use machine intelligence (MI)-based techniques to carry out the recommendation mechanism. Based on the preferences and history, this system is able to know what the users like most. In this work, a recommender system is proposed using the collaborative filtering mechanism for e-Learning course recommendation. This work is focused on MI-based models such as K-nearest neighbor (KNN), Singular Value Decomposition (SVD) and neural network–based collaborative filtering (NCF) models. Here, one lakh of Coursera’s course review dataset is taken from Kaggle for analysis. The proposed work can help learners to select the e-Learning courses as per their preferences. This work is implemented using Python language. The performance of these models is evaluated using performance metrics such as hit rate (HR), average reciprocal hit ranking (ARHR) and mean absolute error (MAE). From the results, it is observed that KNN is able to perform better in terms of higher HR and ARHR and lower MAE values as compared to other models.

A major attraction in Arctic tourism is the presence of indigenous cultures. However, many tourists have only limited opportunities to access indigenous culture and sites, as long as they are not spatially and temporally fixed. This puts museums at the center of attention and gives them a core role in portraying and interpreting indigenous heritage. A dual role with the responsibility to collect, preserve, use, and develop heritage while at the same time appealing to various visitor groups is challenging, not least in a time of Arctification, luring new visitor groups with various touristic imaginaries to the North. This article reports on an assessment of two indigenous museums in Arctic Sweden. The research reveals that the responsible managers at the museums are aware of the dual role of museums, and need to navigate in a complex environment of local and global expectations based on preconceived notions. The museums are important nodes, and contribute to place-making in peripheral localities in the North.

AbstractWe give a simple proof of the strong maximum principle for viscosity subsolutions of fully nonlinear nonhomogeneous degenerate elliptic equations on the form $$ F(x,u,Du,D^{2}u) = 0 $$ F ( x , u , D u , D 2 u ) = 0 under suitable assumptions allowing for non-Lipschitz growth in the gradient term. In case of smooth boundaries, we also prove a Hopf lemma, a boundary Harnack inequality, and that positive viscosity solutions vanishing on a portion of the boundary are comparable with the distance function near the boundary. Our results apply, e.g., to weak solutions of an eigenvalue problem for the variable exponent p-Laplacian.

PurposeThis conceptual paper takes identity, digital technology, young people and education as a combined starting point and suggests how to research young people’s identity practices in and out of school. Today’s young people form their identities in a world that is increasingly imbued by digital technologies. What is evident too is that these technologies and the use of them are not restricted to one single context. Rather, digital technologies mediate multiple contexts simultaneously – to an extent where they collapse. This means that school and leisure time, public and private, digital and analog, virtual and material, time and place, social contexts and audiences, through digital technology, merge in various ways in young people’s identity practices and everyday life.Design/methodology/approachLittle is known about what identity practices in collapsing contexts means to young people in their lives and how educators and others can support them. Most studies to date investigate digital technology use as a discrete phenomenon and few studies concern young people’s identity practices in contexts, as they occur. In an increasingly digital world, where dependency on digital technologies continues this forms an urgent knowledge gap to bridge. In particular to guide educators, and others, who support young people as they live and learn through interconnected spaces in and out of school. The conceptual approach of this paper is of importance to better understand how to bridge this gap.FindingsThis paper suggests a research approach that extends previous research at the intersection of identity, young people, digital technology by outlining extended ways for thinking about identity in a digital world that can be useful for investigating identity as an existential practice, extending beyond identity representations, in conditions mediated by contemporary digital technologies and in collapsing contexts. What is also included are methodological considerations about researching young people, identity and technology as dynamic research objects, rendering a holistic approach.Research limitations/implicationsIt is a conceptual paper that addresses identity, digital technology, young people and education as a combined starting point to outline further research.Originality/valueThe Guided Tour Technique and Social Media Research is suggested as possible methodologies for holistic and ethically sensitive, empirical research on identity, digital technology, young people and education.

Fatal intoxications with opioids are known to be associated with an increased lung weight, as well as with brain and pulmonary edema and urinary retention. However, there is evidence to suggest that fatal intoxications with non-opioid substances are also associated with increased lung weight; however, the latter aspect has not been comprehensively analyzed. To determine to what extent opioid and non-opioid substances are associated with increased lung and brain weight, we studied these organs in cases where the cause of death was attributed to intoxication with a single agent. Using data from cases autopsied at the National Board of Forensic Medicine (NBFM) in Sweden from 2009 through 2019 where the cause of death was attributed to a single substance, we created models of combined lung weight and brain weight. The models used age and sex as predictors as well as nested varying effects for the specific intoxicant and category of intoxicant. Suicidal hanging with negative toxicology cases served as controls. The population majority was male among both intoxications (68%) and controls (83%). The most common single substance group was opioids. All tested substances were associated with heavier lungs than controls, with the largest effect in the opioid group. Our findings show that several substances are associated with increased lung weight and that among intoxication deaths there is no difference in expected brain weight between substances. Hence, heavy lungs, without a reasonable explanation, should prompt a broad toxicological screening.

Plant-based food (PBF) is on the rise as an alternative for animal-based food. Europe is leading in the market size compared with the global market. However, the high failure rate for new food products is challenging the success of new PBF in the market. This paper aims to unravel the key success factors (KSFs) from existing brands, contributing to the knowledge on how to achieve success in PBF market. Two subsequent studies employing online surveys were included, which targeted food expert participants. Study 1 focused on the collection of KSFs related to PBF brands utilizing the card sorting approach. Study 2 employed cluster analysis to further investigate the KSFs among different PBF brands. The findings identified six clusters of KSFs under the external and internal factors supporting the success of the PBF brands. Two (‘Consumer’ and ‘Trend’) and four (‘Ideology’, ‘Marketing strategy’, ‘Innovation management’, and ‘Management structure’) clusters were assigned into external and internal factors, respectively. Furthermore, cluster analysis identified four brand clusters: ‘Mature’, ‘Targeted’, ‘Newcomer’, and ‘Established but diversifying’ clusters. Each brand cluster utilized different KSFs into their strategies; however, both external and internal factors were applied, suggesting that there is no one-size-fits-all KSF to succeed in the market.

The year 2020 was strange for Indigenous movements in Brazil. On-site gatherings were cancelled due to the outbreak of Covid-19. Indigenous movements, in connection with Indigenous media initiatives, aimed at occupying the screens instead. An abundance of live streams popped up on diverse social media platforms. During April 2020, online observations were carried out using an approach inspired by digital ethnography. This article offers a discussion about collecting research data within this changing context. The main aim is to reflect upon online observations as research practice and live streams as sources for scholarly investigation. Additionally, this paper discusses how to think about presence, place and temporality in the research context. 2020 var ett underligt år för urfolksrörelser i Brasilien. På grund av utbrottet av Covid-19 ställdes många av deras planerade sammankomster och träffar in. Istället höll urfolksgrupper massor av “liveströmmar” på sociala medieplattformar. Den här artikeln bygger på digital etnografi där sådana liveströmmar studeras. Online-observationerna genomfördes i april 2020. Artikeln bidrar med en diskussion om att samla in forskningsdata i sådana föränderliga sammanhang. Huvudsyftet är att reflektera över online-observationer som forskningspraxis och liveströmmar som källor för vetenskapliga undersökningar. Dessutom diskuteras hur forskare kan tänka om närvaro, plats och temporalitet i sådana kontexter.

The sagas of Icelanders contain a great wealth of personal names both of historical and fictional nature. Personal names function both as identifiers for individuals but also evoke associations that supersede the name’s lexical or identifying meaning, for example, cultural or social associations such as age, ethnicity, and ideology. This article examines personal names as a source within a source and appraises the use of literary and socio-onomastics in the context of the Íslendingasögur using the example of the elusive difference between “Icelanders” and “Norwegians” in the sagas. The onomastic analysis is based on seven shorter tales and explores the differences in personal names in Icelandic and Norwegian individuals. Based on the onomastic data gathered, this article concludes that there are certain regional differences in name-giving visible in the sagas and that saga authors either had authentic onomastic material at hand or tried to emulate realistic personal names. Islänningasagorna innehåller en stor mängd personnamn av både historisk och fiktiv karaktär. Personnamn fungerar både som identifierare för individer men väcker också associationer som överskuggar namnets lexikala eller identifierande betydelse, såsom kulturella eller sociala associationer som ålder, etnicitet och ideologi. I den här artikeln behandlas personnamn som en källa inom en källa. Även användningen av litterär onomastik och socioonomastik på Islänningasagorna evalueras genom att analysera den svårfångade skillnaden mellan ”islänningar” och ”norrmän” i sagorna. Den onomastiska analysen baseras på sju tåtar och utforskar skillnaderna i personnamn hos isländska och norska individer. Utifrån den onomastiska datan som samlats in drar artikeln slutsatsen att det finns vissa regionala skillnader i namngivning som är synliga i Islänningasagorna och att sagaförfattarna antingen hade autentiskt onomastiskt material till hands eller att de försökte efterlikna autentiska personnamn.

Motion between earth and outer space can be construed in different ways in different languages. The aim of this study is to identify all prepositional constructions used to describe motion from earth to space in English and Swedish and investigate how they contribute to different conceptualizations of earth, space, and the journey in between. It also aims to highlight some challenges of using corpora for cross linguistic research. The data was collected from Corpus of Contemporary American English and Korp and analyzed through the lenses of image-schema and construal. The study shows that there are many ways to construe this type of motion in both languages. Different parts of the journey can be put into focus, and earth and space can be construed in different ways, depending on the perspective of the speaker. The most common constructions in both languages focus on the goal and construe earth and/or space as containers.

While there has been an upsurge of research about human services for male victims of rape, methodological advances are still limited, and significant knowledge gaps remain. Until now, empirical studies have focused almost entirely on human service professionals’ gendered attitudes to try to explain outcomes and victims’ experiences of support. In this article, I argue that research approaches that are based on professionals’ attitudes fail to account for important contextual conditions in policing, healthcare and other human services. My overall aim is thus to introduce greater concern about contextual conditions in human services and provide ways for scholars to approach support for raped men so that different practices, as well as their effects, become visible. To demonstrate the contributions of a practice-based approach to research about support for raped men, an empirical case from a study on police investigation into rape will be analysed and discussed. By using a practice-based approach, it is possible to explore relations between practices performed by organisations, professionals and victims, and highlight the outcomes of such relations. In this way, a practice-based approach can help research progress and contribute to improved services for male rape victims.
