This article reports the results of a systematic review on displaced and refugee-background students’ transitioning and (re-)integration into European higher education (HE). A total of 7082 studies have been assessed for eligibility in six languages. Forty-four empirical studies conducted in 14 countries of the European Higher Education Area (EHEA) between 2014 and 2021 met the inclusion criteria. Evidence from these studies has been extracted, appraised for quality, and synthesised to advance our understanding of how best to support refugee-background students’ HE aspirations. The main contribution of this article is a comprehensive review of support measures and recommendations in nine key areas that were identified as having particular relevance for successful HE participation: recognition of qualifications, entry requirements, reach and relevance of educational offer, costs, precarity and vulnerability, language, transitioning and skills mismatch, resource poverty, and (un)welcoming environments. The reviewed evidence is relevant in varying degrees to higher education institutions across the EHEA and can inform the delivery of targeted responses to refugee-background students’ needs on both HE entry and throughout their educational journey. The article also exposes important knowledge gaps that should be prioritised in future research and highlights some common lessons regarding cross-sector collaboration, long-term planning and support, and the need for a continuous monitoring of student pathways. A novel aspect of this systematic review is also its multilingual search strategy which was designed to correct for the geographical bias toward research produced in Anglophone countries which is often a by-product of English-only search strategies in education research.

The present study explores the case of a transnational Polish family in Norway in which one of the care givers as well as the teenage son underwent a name change after their initial experiences of migration. Drawing on the audio-recorded interactions in the interview situation, the article investigates the identity constructions of the focal participant in his narrative about the name change. To this end, first, the indexicalities of the social identity categoryPoleas constructed in Norwegian media and the participants’ accounts are outlined. Then, against this backdrop, the focal participant’s identity claims as occasioned in the narrative on the name change are discursively analyzed. The analysis shows that the identity claims the focal participant makes aim at dissociating himself from the powerless, stigmatized position of a migrant, in which he was cast upon his arrival in Norway. Furthermore, the study suggests that migrant identity constructions need to be considered against the participants’ lived experiences of migration, larger societal discourses and against participants’ constructions of belonging to imagined communities.

In the following manuscript we propose a quaternionic map which transforms a single quantum state into a bipartite entanglement. Until now such a transformation has not been defined yet. To define such a map, we embed one particle state within the algebra of complex quaternions. Next, on the basis of rotational features of quaternions, we choose a special quaternion which in combination with a quaternion describing a particle state, causes its splitting in a specified direction in 4D space. Finally, we prove that the proposed operation, under several restrictions, always causes bipartite entanglement., Comment: 11 pages

This article applies the concept of metasociolinguistic stance specifically to investigate and analyse how identities and competing discourses can be (re)constructed in metalinguistic talk. In particular, the article analyses how stancetaking can serve as a vessel for constructing language ideologies and identities in metalinguistic talk between a Polish teenager based in Norway and her followers on a social media platform. Inspired by online ethnography, this study combines the observation of online activities, the analysis of screendata, as well as data obtained through direct online and offline discussions with the profile owner. The study showed that the focal participant and her predominantly Polish followers took different metasociolinguistic stances towards the use of Polish and Norwegian in communication between people of Polish origin. While the homeland-based followers constructed an indexical link between ethnic origins and obligatory practice of speaking Polish, the focal participant contested these ideological assumptions and oriented towards a more flexible understanding of the relationship between language and belonging. This contribution shows how social media can serve as a rich research site where the members of diasporic communities and the members of the homeland societies come into contact and interact with each other bringing in different discourses and ideologies into the conversations.

This paper proposes a description of maximally entangled bipartite states within the algebra of biquaternions– C ⨂ H . We assume that a bipartite entanglement is created in a process of splitting one particle into a pair of two indiscernible, yet not identical particles. As a result, we describe an entangled correlation by the use of a division relation and obtain twelve forms of biquaternions, representing pure maximally entangled states. Additionally, we obtain other patterns, describing mixed entangled states. Finally, we show that there are no other maximally entangled states in C ⨂ H than those presented in this work.

This article examines the multilingual repertoires of adult and adolescent Poles living in Norway. The study draws on language portraits and interviews conducted with 14 adults and 12 adolescents living in and around Oslo. The article first discusses multilingualism of the research participants through an analysis of the 26 portraits and then zooms in on the drawings and interview data provided by one family in order to shed light on the ways the participants experience and construct the roles of their different linguistic resources. The study demonstrates that, in general, the research participants are multilingual and that three languages in particular – Polish, English and Norwegian – form an important part of their repertoires. The findings suggest that these linguistic resources and the roles they take on in the individual repertoires, however, might be experienced very differently by the participants. Furthermore, the analysis points to the existence of competing language ideologies among the researched cohort.

Multilingual families and their language policies have attracted considerable attention in recent sociolinguistic work. Adding to this line of research, this article focuses on a case study of a transnational Polish family living in Norway and investigates the role adolescent children may play in the formation of family language policies. To this end the article analyses stances towards language practices at home taken in an interaction between the father and one of the adolescent daughters of the family. The article argues that the perspectives of adolescent children may be of crucial importance for the establishment of family language policies and thus deserve scholarly attention. Methodologically, the article draws attention to family interviews as a useful tool in generating sociolinguistic data for studies of Family Language Policies and advocates an interactional approach to interview data.

This article examines, how agency is constructed by members of two transnational families living in Norway in biographically oriented interviews. We understand agency as realised on the intertwined levels of grammar and meta-agentive discourse. Reports of speakers’ lived language experience and their experiences with family language policies are analysed to demonstrate how speakers use different approaches to realise agency in their narratives. Drawing on data collected through Language Portraits and semi-structured interviews, we focus on how family members perceive and construct their agency when it comes to language learning, maintenance and management.

In response to the paper by Cotnoir and Bacon published in RSL 2/2012, we would like to add some remarks regarding supplementation principles. It is known that in a classical mereology, the Strong Supplementation Principle (SSP) together with antisymmetry enforces the Weak Supplementation Principle (WSP). Instead, in the nonwellfounded mereology, the failure of extensionality causes the failure of antisymmetry (Cotnoir, 2010), hence the investigated model is also nonantisymmetric. Cotnoir supposes that the failure of antisymmetry implies the failure of (WSP) when (PP1) is applied, however gives no explicit argument, which we would like to supply in this paper. Additionally, when (PP2) is applied, (SSP) implies (WSP), hence the failure of antisymmetry does not necessarily imply the failure of (WSP).

A new group of potent inhibitors of glutamine synthetase was designed and synthesized. The X-ray structure of bacterial glutamine synthetase complexed with phosphinothricin was used for computer-aided structure-based design of the inhibitors, in which the methyl group of phosphinothricin was chosen as the modification site. Amino and hydroxyl moieties were introduced into the phosphinic acid portion of the lead molecule to interact with ammonium binding site in the active cleft of the enzyme. Designed compounds were synthesized in enantiomerically pure form analogous to l-glutamic acid. In vitro kinetic studies with Escherichia coli glutamine synthetase confirmed the biological activity of the designed inhibitors, which with K(i) values in the micromolar range (K(i) = 0.59 microM for the most potent compound 2) appear to be slightly weaker inhibitors or equipotent to phosphinothricin.

A strain of Geobacillus caldoxylosilyticus from central heating system water could utilize a number of organophosphonates as the sole phosphorus source for growth at 60°C. During growth on glyphosate, aminomethylphosphonate release to the medium was observed, and in cell extracts, a glyphosate oxidoreductase-type activity, producing stoichiometric amounts of aminomethylphosphonate and glyoxylate from glyphosate, was detectable.

We analyse a time series of the velocities of the low-speed stream measured by the Helios spacecraft in the inner heliosphere, which is a region of space dominated by the solar wind flow. We use a moving average (linear) filter to give a faithful representation of the system's nonlinear behaviour. We have found that trajectories describing the system in phase space asymptotically approach the attractor of the low dimension of 3 to 4. These values are significantly different from the values computed for the surrogate data. Thus these results provide evidence that the inner heliosphere is likely to be a nonlinear chaotic system.

We argue that the inner heliosphere is a chaotic system. We invoke time series analysis of the measurements by the Helios spacecraft (near the Sun) in low-speed streams. The slope of the calculated correlation function saturates at some finite value of the embedding dimension, indicating a low-dimension of the attractor of about 3.5. Furthermore, the largest calculated positive Lyapunov exponent of ~ 1 5 bits per data sample (40.5 s) shows sensitive dependence on initial conditions. This means that the predictability of the system is limited to about 1 h.
